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.
The key feature of self-aligning bearings is the spherical shape of the outer ring raceway. This design allows the bearing to accommodate angular misalignment between the shaft and the housing, as well as any axial misalignment or shaft deflection that may occur during operation.
- Functioning in Machinery:
Self-aligning bearings function in machinery by providing several important benefits:
- Misalignment Compensation: Self-aligning bearings can compensate for angular misalignment between the shaft and the housing. This is particularly useful in applications where there may be slight misalignments due to manufacturing tolerances, thermal expansion, or shaft deflection under load. The self-aligning capability allows the bearing to maintain proper alignment and minimize stress on the bearing components.
- Reduced Friction and Wear: The ability of self-aligning bearings to accommodate misalignment helps reduce friction and wear. Misalignment can cause uneven loading and increased stress on the bearing, leading to premature failure. By allowing the bearing to adjust its position, self-aligning bearings distribute the load more evenly, reducing friction and wear on the rolling elements and raceways.
- Shock and Vibration Absorption: Self-aligning bearings can also absorb shocks and vibrations that may occur during operation. The spherical shape of the outer ring raceway allows the bearing to move and adjust its position, effectively absorbing and dampening the impact of shocks and vibrations. This helps improve the overall stability, smoothness, and durability of the machinery.
- Easy Installation and Maintenance: Self-aligning bearings are relatively easy to install and maintain. The self-aligning capability simplifies the alignment process during installation, as slight misalignments can be accommodated. Additionally, regular maintenance tasks, such as re-greasing or replacement of the bearing, can be performed more easily due to the flexibility and adjustability of self-aligning bearings.
Overall, self-aligning bearings play a crucial role in machinery by allowing for misalignment compensation, reducing friction and wear, absorbing shocks and vibrations, and providing ease of installation and maintenance. These features contribute to improved performance, reliability, and durability of the machinery in various applications.
