Product Description
Self-aligning ball bearings are bearings with steel balls and cage assemblies between the 2 raceways inner ring and spherical raceways outer ring.
Self-aligning ball bearing has 2 structures of cylindrical hole and conical hole. The material of the cage is steel plate, synthetic resin, engineering plastic and so on.
The self-aligning ball bearing can have sealing structure similar to the deep groove ball bearing, but it will affect the self-alignment of the bearings.
Self-aligning ball bearings mainly bear radial load, and can bear small axial load at the same time. It can’t bear pure axial load. Due to the structure, the limit speed of self-aligning ball bearings is relatively low.
The characteristic of self-aligning ball bearing is that the outer ring raceway is spherical.Since the curvature center of the outer ring raceway surface is consistent with the bearing center, it has the self-aligning function, allowing the axis of the inner ring, balls and cage to deflect around the bearing center, which can compensate for the errors caused by the misalignment and the deflection of the shaft and the outer casing, but the relative inclination of the inner and outer rings should not exceed 3 degrees. This type of bearing is mostly used on double support shafts that are prone to bending under load, and in components where the housing seat hole cannot be strictly coaxial.
Main applications:
Metallurgy, rolling mill, mining, petroleum, paper, cement, textile, sugar extraction and other industries and general machinery.

Can you describe the load-carrying capacity and load ratings of self-aligning bearings?
Self-aligning bearings are designed to carry both radial and axial loads, and their load-carrying capacity is an essential consideration for their proper selection and application. Here’s a detailed description of the load-carrying capacity and load ratings of self-aligning bearings:
- Radial Load Capacity:
The radial load capacity of a self-aligning bearing refers to its ability to carry loads that act perpendicular to the axis of rotation. It is influenced by factors such as bearing geometry, material properties, and internal design. Self-aligning bearings, particularly spherical roller bearings, are known for their high radial load-carrying capacity. This is due to their construction that includes multiple rows of robust rolling elements and optimized raceway profiles. The larger contact area between the rolling elements and raceways allows for efficient load distribution, enabling the bearing to handle substantial radial loads.
- Axial Load Capacity:
The axial load capacity of a self-aligning bearing refers to its ability to carry loads that act parallel to the axis of rotation. The axial load-carrying capacity depends on the bearing type and design, as well as the arrangement of rolling elements. Self-aligning thrust roller bearings, for example, are specifically designed to handle significant axial loads. They utilize cylindrical or tapered rolling elements arranged in a specific orientation to withstand axial forces. Self-aligning ball bearings can also carry moderate axial loads in addition to their primary radial load-carrying capacity.
- Dynamic Load Rating:
The dynamic load rating of a self-aligning bearing is a standardized value that indicates the maximum load that the bearing can sustain for a specified number of rotations or operating hours without experiencing premature fatigue failure. It is expressed in terms of the calculated dynamic equivalent radial or axial load, which takes into account the actual load distribution within the bearing. The dynamic load rating is typically provided by the manufacturer and allows engineers to compare and select bearings based on their expected performance under dynamic operating conditions.
- Static Load Rating:
The static load rating of a self-aligning bearing represents the maximum load that the bearing can sustain without permanent deformation or excessive stress when the bearing is stationary or subjected to very slow rotations. It is typically higher than the dynamic load rating. The static load rating is an important consideration for applications where the bearing may be subjected to prolonged static or slow-speed conditions, such as in machinery that operates with intermittent or intermittent rotational motion.
It is important to note that the load-carrying capacity and load ratings provided by manufacturers are based on standardized testing methods and assumptions about operating conditions. Actual load capacity can be influenced by factors such as temperature, lubrication, misalignment, and operating speed. Therefore, it is crucial to consider the specific application requirements and consult the manufacturer’s technical data and guidelines when selecting a self-aligning bearing to ensure its suitability and optimal performance.
