How do self-aligning bearings compensate for misalignment in machinery?
Self-aligning bearings are designed to compensate for misalignment in machinery, allowing them to accommodate angular misalignment, axial misalignment, and shaft deflection. Here’s a detailed explanation of how self-aligning bearings achieve misalignment compensation:
Spherical Outer Ring Raceway:
The key feature of self-aligning bearings is their spherical outer ring raceway. This raceway is designed to have a curvature that matches the spherical shape of the rolling elements, such as balls or rollers. The spherical outer ring raceway allows the bearing to tilt or swivel in response to misalignment, enabling it to self-align with the mating components.
Rolling Element Design:
The rolling elements in self-aligning bearings are carefully designed to facilitate misalignment compensation. For example, spherical roller bearings have barrel-shaped rollers, while self-aligning ball bearings have two rows of balls. These rolling elements can adjust their positions within the bearing, redistributing the load and accommodating misalignment between the shaft and the housing.
Internal Clearance:
Self-aligning bearings often have a larger internal clearance compared to fixed or non-self-aligning bearings. This additional clearance provides space for the bearing components to move and adjust their positions during misalignment. The internal clearance allows the bearing to properly distribute the load, reduce friction, and prevent excessive stress on the rolling elements and raceways.
Flexible Mounting:
Self-aligning bearings offer flexibility in their mounting arrangements. They can tolerate slight misalignments during installation, which simplifies the alignment process. This flexibility is particularly beneficial in applications where thermal expansion, shaft deflection, or other dynamic factors may cause misalignment during operation.
Load Distribution:
When misalignment occurs, self-aligning bearings distribute the load more evenly across the rolling elements and raceways. This even load distribution helps reduce localized stresses and minimizes the risk of premature failure. By accommodating misalignment, self-aligning bearings allow for smoother operation and improved reliability in machinery.
It’s important to note that while self-aligning bearings can compensate for certain degrees of misalignment, there are limits to their misalignment capability. Excessive misalignment beyond the bearing’s specified limits can lead to increased friction, reduced bearing life, and potential damage. Therefore, it is crucial to follow the manufacturer’s guidelines and recommendations regarding misalignment limits and operating conditions to ensure optimal performance and longevity of self-aligning bearings in machinery.

Can you describe the various types of seals and shields used with self-aligning bearings for contamination prevention?
Yes, here’s a detailed description of the various types of seals and shields used with self-aligning bearings for contamination prevention:
Contact Seals:
Contact seals, also known as lip seals or radial seals, are commonly used with self-aligning bearings to prevent the ingress of contaminants. These seals feature a flexible lip that makes contact with the inner ring of the bearing, creating a barrier against dust, dirt, water, and other external substances. Contact seals provide effective contamination prevention but may introduce slightly higher friction due to the contact between the seal lip and the bearing surface. They are typically made of rubber or synthetic materials and offer good sealing performance in most operating conditions.
Felt Seals:
Felt seals are simple and cost-effective sealing solutions used with self-aligning bearings. They consist of a felt material that is compressed against the bearing inner ring or housing to create a barrier against contaminants. Felt seals are commonly used in applications with low to moderate speeds and light contamination levels. While they offer basic protection against solid particles, they may not provide effective sealing against liquids or fine particles.
Metallic Shields:
Metallic shields, also known as metal shields or non-contact shields, are used to protect self-aligning bearings from solid contaminants such as dust and dirt. These shields are typically made of steel or other metals and are designed to fit closely to the bearing inner ring without making contact. Metallic shields provide effective protection while minimizing friction and heat generation. They are suitable for high-speed applications where low torque and minimal drag are desired.
Rubber Shields:
Rubber shields, also known as non-contact seals or labyrinth seals, consist of a rubber or elastomeric material that forms a barrier around the bearing without making direct contact. Rubber shields are designed with a labyrinth-like structure that uses multiple barriers to prevent the entry of contaminants. These shields provide effective sealing against both solid particles and liquids while still allowing for low-friction operation. Rubber shields are commonly used in applications where low torque, minimal drag, and enhanced contamination protection are required.
Hybrid Seals:
Hybrid seals combine the advantages of different sealing technologies to provide optimal contamination prevention. These seals may incorporate a combination of contact seals, non-contact shields, or additional features such as flingers or slingers. Hybrid seals are designed to provide enhanced protection against a wide range of contaminants while minimizing friction and maintaining low torque. They are often used in demanding applications where a high level of sealing performance is required.
Additional Features:
In addition to the primary seals and shields mentioned above, some self-aligning bearings may incorporate additional features to enhance contamination prevention. These features include flingers, which are rotating discs or rings that help to deflect contaminants away from the bearing; slingers, which are similar to flingers but operate by centrifugal force; and specialized coatings or surface treatments that provide enhanced resistance to corrosion or chemical attack.
It’s important to consult the bearing manufacturer’s specifications and guidelines to select the appropriate type of seal or shield for a specific self-aligning bearing and its operating conditions. By choosing the right sealing solution, engineers can effectively prevent contamination and prolong the service life of self-aligning bearings in various applications.

Shaft and Housing Tolerances: Check the shaft and housing tolerances to ensure they comply with the specifications provided by the bearing manufacturer. Proper tolerances help achieve the correct fit and prevent excessive clearance or interference.
Shaft and Housing Preparation: Clean the shaft and housing surfaces and remove any burrs or rough edges that could interfere with the bearing’s seating. Ensure that the shaft and housing are machined to the recommended tolerances and finishes.
Mounting Method: There are various methods for mounting self-aligning bearings, including press fitting, thermal expansion, and hydraulic mounting. Follow the manufacturer’s instructions and recommended mounting method to ensure a secure and accurate fit.
Sealing: If the self-aligning bearing has integral seals or shields, ensure that they are correctly positioned and aligned during installation. Proper sealing helps protect the bearing against contaminants and extends its service life.
Tightening: When tightening the bearing onto the shaft or in the housing, use the recommended torque values provided by the manufacturer. Over-tightening can lead to excessive preload or damage, while under-tightening can result in insufficient seating and compromised performance.
Alignment Considerations:
Proper alignment is crucial for self-aligning bearings to function optimally. Here are some alignment considerations:
Angular Misalignment: Self-aligning bearings can accommodate angular misalignment to a certain degree. However, it is important to keep the misalignment within the manufacturer’s specified limits to prevent excessive stress and premature wear.
Shaft Deflection: Consider the potential shaft deflection that may occur during operation and ensure that the self-aligning bearing can handle the expected deflection without exceeding its capacity. This may involve selecting a bearing with appropriate load-carrying capacity and considering additional support or stabilization measures.
Alignment Verification: After installation, verify the alignment of the self-aligning bearing by measuring the axial and radial runout using appropriate alignment tools. Adjust the positioning if necessary to achieve the desired alignment within the specified tolerances.
By following these installation and alignment considerations, you can ensure the proper fit, alignment, and performance of self-aligning bearings. Adhering to the manufacturer’s guidelines and best practices helps maximize the lifespan and reliability of the bearings in various applications.
How do self-aligning bearings differ from fixed or non-self-aligning bearings?
Self-aligning bearings differ from fixed or non-self-aligning bearings in several ways. Here’s a detailed explanation of the differences between these types of bearings:
Design and Construction:
The design and construction of self-aligning bearings are distinct from fixed or non-self-aligning bearings. Self-aligning bearings have a spherical outer ring raceway, which allows for misalignment compensation. In contrast, fixed or non-self-aligning bearings typically have a cylindrical or tapered outer ring raceway, designed for precise alignment between the shaft and the housing.
Misalignment Compensation:
The primary difference between self-aligning bearings and fixed or non-self-aligning bearings is their ability to compensate for misalignment. Self-aligning bearings can accommodate angular misalignment, axial misalignment, and shaft deflection, whereas fixed or non-self-aligning bearings have limited tolerance for misalignment and require precise alignment during installation.
Load Distribution:
Self-aligning bearings distribute the load more evenly across the rolling elements and raceways, thanks to their ability to accommodate misalignment. This helps reduce localized stresses and minimize the risk of premature failure. Fixed or non-self-aligning bearings, without the ability to compensate for misalignment, may experience uneven loading and increased stress on specific areas, leading to accelerated wear and potential failure.
Friction and Wear:
Due to their misalignment compensation capability, self-aligning bearings help reduce friction and wear. Misalignment in fixed or non-self-aligning bearings can cause increased friction and localized wear, leading to reduced bearing life. Self-aligning bearings distribute the load more evenly, minimizing friction and wear on the rolling elements and raceways, resulting in improved reliability and longevity.
Application Range:
The different design and misalignment compensation capability of self-aligning bearings make them suitable for a broader range of applications compared to fixed or non-self-aligning bearings. Self-aligning bearings are commonly used in applications where misalignment is expected, such as heavy machinery, conveyor systems, and mining equipment. Fixed or non-self-aligning bearings are typically employed in applications that require precise alignment, such as machine tools or high-precision equipment.
Installation and Maintenance:
Self-aligning bearings offer easier installation and maintenance compared to fixed or non-self-aligning bearings. The self-aligning capability of these bearings allows for more flexibility during the installation process, accommodating slight misalignments. In contrast, fixed or non-self-aligning bearings require careful alignment procedures to ensure proper functioning. Additionally, self-aligning bearings are often designed for easier maintenance, enabling tasks such as re-greasing or replacement without extensive disassembly.
In summary, self-aligning bearings differ from fixed or non-self-aligning bearings in their design, misalignment compensation capability, load distribution, friction and wear characteristics, application range, and ease of installation and maintenance. These differences make self-aligning bearings particularly suitable for applications where misalignment is expected or dynamic operating conditions are present.
Angular contact ball bearings are CZPT to support radial load and axial load. Single row angular contact ball bearings can only support axial load in single direction, it adopts mounting in pair. As matched pairs of bearings, preload for them is more convenient. Its retainer are made of brass, synthetic resins or others subject to individual bearing feature and application conditions.

It’s important to consider the magnitude and type of misalignment that the bearing will experience. Some self-aligning bearings can accommodate larger misalignments, while others are designed for smaller or specific types of misalignments, such as angular or parallel misalignment. Understanding the misalignment characteristics of the application is essential to select the appropriate self-aligning bearings that can effectively handle the expected misalignment conditions.
Load Capacity and Dynamic Performance:
In applications with challenging operating conditions, it’s crucial to assess the load capacity and dynamic performance requirements of the self-aligning bearings. Heavy loads, shock loads, or vibrations can significantly affect the bearing’s performance and service life. It’s important to choose self-aligning bearings with adequate load-carrying capacity, high shock resistance, and robust construction to withstand the demanding conditions. Additionally, the dynamic performance of the bearing, including factors such as rotational speed, acceleration, and deceleration, should be carefully evaluated to ensure that the selected bearings can meet the application’s performance requirements.
Sealing and Contamination Prevention:
In challenging operating conditions, effective sealing and contamination prevention become crucial for self-aligning bearings. Dust, dirt, moisture, and other contaminants can significantly impact the bearing’s performance and service life. It’s important to select self-aligning bearings with appropriate sealing solutions, such as contact seals, non-contact seals, or hybrid seals, depending on the specific application requirements. These seals help prevent the ingress of contaminants and maintain the integrity of the bearing’s internal components, ensuring reliable operation even in harsh environments.
Lubrication and Maintenance:
Lubrication and maintenance practices are critical considerations for self-aligning bearings in challenging operating conditions. Proper lubrication selection, including the choice of lubricant type, viscosity, and replenishment frequency, is essential to ensure optimal bearing performance and minimize the risk of premature wear or failure. Additionally, adhering to appropriate maintenance practices, such as regular inspections, re-lubrication, and monitoring of operating conditions, can help identify any potential issues early on and prevent costly downtime or unexpected failures.
By considering these specific factors and requirements, engineers can choose the most suitable self-aligning bearings for applications with challenging operating conditions or varying misalignment requirements.

Can you explain the installation and alignment considerations for self-aligning bearings?
Proper installation and alignment are crucial for the optimal performance and longevity of self-aligning bearings. Here’s a detailed explanation of the installation and alignment considerations:
Pre-Installation Preparation:
Prior to the installation of self-aligning bearings, it is essential to ensure a clean and suitable working environment. Here are some key considerations:
Cleanliness: The work area should be clean and free from dust, dirt, and contaminants to prevent the ingress of foreign particles during the installation process.
Tools and Equipment: Prepare the necessary tools and equipment required for the installation, including suitable lifting devices, torque wrenches, and lubrication apparatus.
Inspection: Thoroughly inspect the bearing and its components for any signs of damage or defects. Replace any worn or damaged parts before proceeding with the installation.
Lubrication: Apply the recommended lubricant to the bearing and ensure that it is properly distributed before installation. Lubrication helps reduce friction, prevent excessive wear, and facilitate smooth operation.
Mounting Considerations:
When mounting self-aligning bearings, it is important to follow certain guidelines to ensure proper fit and alignment:
Shaft and Housing Tolerances: Check the shaft and housing tolerances to ensure they comply with the specifications provided by the bearing manufacturer. Proper tolerances help achieve the correct fit and prevent excessive clearance or interference.
Shaft and Housing Preparation: Clean the shaft and housing surfaces and remove any burrs or rough edges that could interfere with the bearing’s seating. Ensure that the shaft and housing are machined to the recommended tolerances and finishes.
Mounting Method: There are various methods for mounting self-aligning bearings, including press fitting, thermal expansion, and hydraulic mounting. Follow the manufacturer’s instructions and recommended mounting method to ensure a secure and accurate fit.
Sealing: If the self-aligning bearing has integral seals or shields, ensure that they are correctly positioned and aligned during installation. Proper sealing helps protect the bearing against contaminants and extends its service life.

How do self-aligning bearings compensate for misalignment in machinery?
Self-aligning bearings are designed to compensate for misalignment in machinery, allowing them to accommodate angular misalignment, axial misalignment, and shaft deflection. Here’s a detailed explanation of how self-aligning bearings achieve misalignment compensation:
Spherical Outer Ring Raceway:
The key feature of self-aligning bearings is their spherical outer ring raceway. This raceway is designed to have a curvature that matches the spherical shape of the rolling elements, such as balls or rollers. The spherical outer ring raceway allows the bearing to tilt or swivel in response to misalignment, enabling it to self-align with the mating components.
Rolling Element Design:
The rolling elements in self-aligning bearings are carefully designed to facilitate misalignment compensation. For example, spherical roller bearings have barrel-shaped rollers, while self-aligning ball bearings have two rows of balls. These rolling elements can adjust their positions within the bearing, redistributing the load and accommodating misalignment between the shaft and the housing.
Internal Clearance:
Self-aligning bearings often have a larger internal clearance compared to fixed or non-self-aligning bearings. This additional clearance provides space for the bearing components to move and adjust their positions during misalignment. The internal clearance allows the bearing to properly distribute the load, reduce friction, and prevent excessive stress on the rolling elements and raceways.
Flexible Mounting:
Self-aligning bearings offer flexibility in their mounting arrangements. They can tolerate slight misalignments during installation, which simplifies the alignment process. This flexibility is particularly beneficial in applications where thermal expansion, shaft deflection, or other dynamic factors may cause misalignment during operation.
Load Distribution:
When misalignment occurs, self-aligning bearings distribute the load more evenly across the rolling elements and raceways. This even load distribution helps reduce localized stresses and minimizes the risk of premature failure. By accommodating misalignment, self-aligning bearings allow for smoother operation and improved reliability in machinery.
It’s important to note that while self-aligning bearings can compensate for certain degrees of misalignment, there are limits to their misalignment capability. Excessive misalignment beyond the bearing’s specified limits can lead to increased friction, reduced bearing life, and potential damage. Therefore, it is crucial to follow the manufacturer’s guidelines and recommendations regarding misalignment limits and operating conditions to ensure optimal performance and longevity of self-aligning bearings in machinery.

Product Description
Self Aligning Ball Bearings
Self aligning ball bearings have 2 rows of balls, a common sphered raceway in the outer ring and 2 deep uninterrupted raceway grooves in the inner ring. Self aligning ball bearings are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection or housing deformations. Self aligning ball bearings are suitable for applications where the shaft relative to the housing bore is prone to angular misalignments. Under normal loads, depending on the dimensional series, the maximum permissible angular misalignment is approximately 2° to 4°. These bearings are available in open and sealed versions and inner rings with a cylindrical or tapered bore.

What are self-aligning bearings, and how do they function in machinery?
Self-aligning bearings are a type of rolling contact bearings that are designed to accommodate misalignment between the shaft and the housing in machinery. They are commonly used in applications where shaft deflection, shaft misalignment, or mounting errors are expected.
Here’s a detailed explanation of self-aligning bearings and their functioning in machinery:
Design and Construction:
Self-aligning bearings consist of two main components: an inner ring with the rolling elements and an outer ring with a spherical raceway. The inner ring is typically mounted on the rotating shaft, while the outer ring is mounted in the housing. The rolling elements, usually balls or rollers, are positioned between the inner and outer rings to facilitate smooth rotation.

Can you describe the various types of seals and shields used with self-aligning bearings for contamination prevention?
Yes, here’s a detailed description of the various types of seals and shields used with self-aligning bearings for contamination prevention:
Contact Seals:
Contact seals, also known as lip seals or radial seals, are commonly used with self-aligning bearings to prevent the ingress of contaminants. These seals feature a flexible lip that makes contact with the inner ring of the bearing, creating a barrier against dust, dirt, water, and other external substances. Contact seals provide effective contamination prevention but may introduce slightly higher friction due to the contact between the seal lip and the bearing surface. They are typically made of rubber or synthetic materials and offer good sealing performance in most operating conditions.
Felt Seals:
Felt seals are simple and cost-effective sealing solutions used with self-aligning bearings. They consist of a felt material that is compressed against the bearing inner ring or housing to create a barrier against contaminants. Felt seals are commonly used in applications with low to moderate speeds and light contamination levels. While they offer basic protection against solid particles, they may not provide effective sealing against liquids or fine particles.
Metallic Shields:
Metallic shields, also known as metal shields or non-contact shields, are used to protect self-aligning bearings from solid contaminants such as dust and dirt. These shields are typically made of steel or other metals and are designed to fit closely to the bearing inner ring without making contact. Metallic shields provide effective protection while minimizing friction and heat generation. They are suitable for high-speed applications where low torque and minimal drag are desired.
Rubber Shields:
Rubber shields, also known as non-contact seals or labyrinth seals, consist of a rubber or elastomeric material that forms a barrier around the bearing without making direct contact. Rubber shields are designed with a labyrinth-like structure that uses multiple barriers to prevent the entry of contaminants. These shields provide effective sealing against both solid particles and liquids while still allowing for low-friction operation. Rubber shields are commonly used in applications where low torque, minimal drag, and enhanced contamination protection are required.
Hybrid Seals:
Hybrid seals combine the advantages of different sealing technologies to provide optimal contamination prevention. These seals may incorporate a combination of contact seals, non-contact shields, or additional features such as flingers or slingers. Hybrid seals are designed to provide enhanced protection against a wide range of contaminants while minimizing friction and maintaining low torque. They are often used in demanding applications where a high level of sealing performance is required.
Additional Features:
In addition to the primary seals and shields mentioned above, some self-aligning bearings may incorporate additional features to enhance contamination prevention. These features include flingers, which are rotating discs or rings that help to deflect contaminants away from the bearing; slingers, which are similar to flingers but operate by centrifugal force; and specialized coatings or surface treatments that provide enhanced resistance to corrosion or chemical attack.
It’s important to consult the bearing manufacturer’s specifications and guidelines to select the appropriate type of seal or shield for a specific self-aligning bearing and its operating conditions. By choosing the right sealing solution, engineers can effectively prevent contamination and prolong the service life of self-aligning bearings in various applications.

Types of Ball Bearings
In their most basic form, Ball Bearings have one common feature – they are made of steel. The majority of these bearings are made of 52100 steel, which has one percent chromium and one percent carbon. The steel can be hardened by heat trea tment. 440C stainless steel is used for rusting problems. A cage around the ball balls is traditionally made from thin steel. However, some bearings use molded plastic cages to save money and friction.
Single-row designs
Steel linear translation stages often use single-row designs for ball bearings. These types of bearings provide smooth linear travel and can withstand high loads. The material steel has a high modulus of elasticity and a high stiffness, as well as a lower thermal expansion than aluminum. For these reasons, steel is the material of choice for a ball bearing in a typical user environment. Single-row designs for ball bearings are also suitable for applications in humid or corrosive environments. Single-row designs for ball bearings are available in a variety of sizes and are axially adjustable. They have a high radial capacity, but require relatively little space. Single-row deep groove ball bearings with snap rings are STN 02 4605 or R47, respectively. Bearings with snap rings are identified by a suffix such as NR. They may not have seals or shields installed. These single-row angular contact ball bearings are capable of supporting axial and radial loads. In a two-raceway arrangement, the radial load on bearing A causes a radial load to act on bearing B. Both axial and radial forces are transmitted between single-row angular contact ball bearings, and the resulting internal force must be taken into account to calculate equivalent dynamic bearing loads P. Single-row deep groove ball bearings are the most common type of ball bearings. These bearings are designed with only one row of rolling elements. The single-row design is simple and durable, which makes it ideal for high-speed applications. Single-row designs for ball bearings are also available in various bore sizes. They can also come in a variety of shapes and are non-separable. If you need a high-speed bearing, you may want to opt for a double-row design. In addition to single-row designs for ball bearings, you can choose ceramic or steel ball bearings. Ceramic balls are considerably harder than steel balls, but they are not as hard as steel. Hence, ceramic bearings are stiffer than steel ball bearings, resulting in increased stress on the outer race groove and lower load capacity. This is a great benefit for those who need the bearings to be lightweight and strong. The difference between single-row and double-row designs is in the way that the inner and outer ring are installed. A single-row design places the inner ring in an eccentric position relative to the outer ring. The two rings are in contact at one point, which causes a large gap in the bearing. The balls are then inserted through the gap. As a result, the balls are evenly distributed throughout the bearing, which forces the inner and outer rings to become concentric. Deep-groove ball bearings are one of the most popular types of ball bearings. They are available in different designs, including snap-ring, seal and shield arrangements. The race diameter of a deep-groove ball bearing is close to the ball’s diameter. These types of bearings are suited for heavy loads, and their axial and radial support are excellent. Their main drawback is that the contact angle cannot be adjusted to accommodate a wide range of relative loads.
Ceramic hybrid ball bearings
Hybrid ball bearings with ceramic balls have numerous advantages. They feature improved kinematic behavior and require less lubrication. Consequently, they can reduce operating costs. Additionally, their low thermal expansion coefficient allows for smaller changes in contact angle and preload variations, and they can retain tolerances. Furthermore, ceramic hybrid ball bearings have significantly increased life spans compared to conventional steel-steel ball bearings, with up to 10 times the lifespan. Although ceramic bearings can be used in automotive applications, many people believe that they’re a poor choice for bicycle hubs. They don’t reduce weight and only work well in high-rpm environments. As a result, many cyclists don’t even bother with ceramic-based bearings. However, both Paul Lew and Alan are of the opinion that ceramic bearings are best suited for industrial or medical equipment applications. Furthermore, Paul and Alan believe that they are ideal for high-altitude drone motors. Another advantage of ceramic hybrid ball bearings is that they use less friction than conventional steel-based balls. They are also more durable, requiring less lubrication than steel-based bearings. Furthermore, the lower friction and rolling resistance associated with ceramic-based ball bearings means that they can last ten times longer than steel-based bearings. A ceramic-based hybrid ball bearing can be used for applications where speed and lubrication are critical. Ceramic hybrid ball bearings feature both steel and silicon nitride balls. Silicon nitride balls have 50% more modulus of elasticity than steel balls and can improve accuracy and precision. Ceramic balls also have a smoother surface finish than steel balls, which reduces vibration and spindle deflection. These benefits result in increased speed and improved production quality. In addition to this, ceramic balls can also reduce the operating temperature, enhancing the work environment. Hybrid bearings are a popular alternative to steel bearings. They have some benefits over traditional steel bearings, and are becoming a popular choice for engineered applications. Hybrid bearings are ideal for high speed machines. The material used to manufacture ceramic balls is a high-quality alloy, and is comparatively inexpensive. But you must understand that lubrication is still necessary for hybrid bearings. If you are not careful, you may end up wasting money. These ball bearings can be used in many industries and applications, and they are widely compatible with most metals. The main advantage of hybrid ball bearings is that they are very durable. While steel balls tend to corrode and wear out, ceramic ball bearings can withstand these conditions while minimizing maintenance and replacement costs. The benefits of hybrid ball bearings are clear. So, consider switching to these newer types of ball bearings.
Self-aligning ball bearings
Self-aligning ball bearings are a good choice for many applications. They are a great alternative to traditional ball bearings, and they are ideal for rotating applications in which the shaft must move in several directions. They are also ideal for use in rotating parts where a tight tolerance is necessary. You can choose between two types: plain and flex shaft. Read on to find out which one will suit your needs. Self-aligning ball bearings are designed with a higher axial load carrying capacity than single-row radial deep groove ball bearings. The amount of axial load carrying capacity is dependent upon the pressure angle. These bearings have a hollow raceway in the outer ring that allows the inner ring to pivot without friction. They are often used for high-speed applications. Because of their design, they are highly accurate. Self-aligning ball bearings are radial bearings that feature two rows of balls in a spherical outer ring. They also feature two deep uninterrupted raceway grooves in the inner ring. Their unique features make them an excellent choice for applications where shaft deflection is a significant factor. Despite their small size, they have a high level of precision and can withstand heavy loads. Self-aligning ball bearings can compensate for misalignment in shaft applications. The inner ring and ball assembly are positioned inside an outer ring containing a curved raceway. This spherical design allows the balls and cage to deflect and re-align around the bearing center. These bearings are also ideal for applications where shaft deflection is significant, such as in simple woodworking machinery. Another type of self-aligning ball bearing uses a common concave outer race. Both balls and outer races automatically compensate for angular misalignment caused by machining, assembly, and deflections. Compared to spherical rollers, they have lower frictional losses than their spherical counterparts. Self-alignment ball bearings also have lower vibration levels compared to other types of bearings. Self-aligning ball bearings operate in misaligned applications because their spherical outer raceway can accommodate misalignment. This design allows them to work in applications where shaft deflection or housing deformation is common. They are therefore more suitable for low to medium-sized loads. The only real drawback to self-aligning ball bearings is their price. If you need to purchase a self-aligning ball bearing for your next project, you can expect to pay around $1500.
