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 perform in applications with varying loads and misalignment challenges?
Self-aligning bearings are specifically designed to perform exceptionally well in applications with varying loads and misalignment challenges. Here’s an in-depth explanation of their performance characteristics:
- Misalignment Compensation:
Self-aligning bearings are capable of accommodating various types of misalignment, including angular misalignment and shaft deflection. They feature a design that incorporates two rows of rolling elements, such as balls or rollers, and a spherical outer ring raceway. This design allows the bearing to self-align, adapting to misalignment caused by factors such as shaft deflection, mounting errors, thermal expansion, and vibrations. Self-aligning bearings can handle misalignment within certain limits, maintaining proper alignment between the mating components and minimizing additional stresses on the bearing.
- Load-Carrying Capacity:
Self-aligning bearings are engineered to handle high loads, both radial and axial. They have a robust construction with larger rolling elements and increased contact area, enabling them to distribute the load more effectively. This enhanced load-carrying capacity makes self-aligning bearings suitable for applications where varying loads are encountered. Whether it’s fluctuating radial loads, axial loads, or a combination of both, self-aligning bearings can handle the dynamic forces and provide reliable performance.
- Flexibility and Versatility:
Self-aligning bearings offer flexibility and versatility in applications with varying loads and misalignment challenges. They can operate in conditions where shafts are not perfectly aligned or where there are slight shaft movements. This flexibility allows for easier installation and alignment adjustments, reducing the time and effort required for precise positioning of the bearing. Additionally, self-aligning bearings are available in different designs and configurations, including ball bearings and roller bearings, providing options to match specific application requirements.
- Reduced Friction and Heat Generation:
Self-aligning bearings are designed to minimize friction and heat generation during operation. The rolling elements and raceways are precisely engineered to reduce contact stresses and optimize the distribution of forces. This results in lower friction levels and reduced heat buildup, enhancing the overall efficiency and reliability of the bearing in applications where varying loads and misalignment challenges are present.
