Self Aligning Ball Bearings


Self-aligning ball bearings are double row with inner ring raceways similar to a double row deep grove ball bearing whereas the outer ring features a common spherical raceway. The center of the spherical curvature coincides with the bearing center and therefore, are internally self aligning.

These 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 degrees.

The bearings are available in open and sealed versions and inner rings with a cylindrical or tapered bore.
