Self Aligning Ball Bearing

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. Therefore, the axis of the inner ring, balls, and cage can deflect to some extent around the bearing center.

The bearings are insensitive to angular misalignment of the shaft and housing caused by machining or mounting error is automatically corrected. Under normal loads, depending on the dimensional series, the maximum permissible angular misalignment is approximately 2 to 4 degrees.

BMD produces a wide range of Self Aligning Ball Bearings in both Cylindrical Bore and Tapered Bore.
