Self-aligning Ball
Bearings
Self-aligning ball bearings consist of an inner ring with two raceways, a spherical outer ring Self-aligning ball bearings consist of an inner ring with two raceways, an outer ring with a spherical raceway, two rows of balls, and a cage. Their self-aligning design compensates for shaft deflection and mounting misalignment. They are widely used in conveyors, textile machinery, agricultural equipment, fans, and other applications requiring smooth, low-friction operation.
