Self-aligning ball bearings have two rows of spherical rolling elements, with a common spherical raceway in the outer ring and two deep groove continuous raceways in the inner ring. They can be open or sealed. This type of bearing allows for relatively large angular displacement of the shaft relative to the housing, such as that caused by shaft deflection.
Features and Advantages
Accommodates Static and Dynamic Misalignment
Like spherical roller bearings or CARB bearings, this type of bearing has self-aligning capability.
Excellent High-Speed Performance
Self-aligning ball bearings generate the lowest friction compared to any other type of rolling bearing, resulting in low temperature rise even at high speeds.
Minimum Maintenance Requirements
Bearings operate at lower temperatures due to reduced heat generation, extending bearing service life and maintenance intervals.
Low Friction
The clearance fit between rolling elements and outer ring reduces friction and frictional heat.
Excellent Light Load Performance
Self-aligning ball bearings have low minimum load requirements.
Low Noise
For example, self-aligning ball bearings can reduce noise and vibration levels in fans.
