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.

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.
