Double Row Self-Aligning Ball Bearings

Demand For more informations contact us

The double row self-aligning ball bearings have two rows of balls and a spherical raceway on the outer ring. Certain misalignment of the inner ring referring to the outer ring around the bearing centre will work independently of the bearing operation.

The bearings are used for applications which presume certain bore misalignment in the bearing housings or deflaction and oscillation of the shaft at long mutual distance of the bearing. The bearings are non-separable. With respect to their small contact angle and the imperfect conformity of the balls to the raceways, they are not recommended for carrying larger axial forces. The bearings are manufactured with cylindrical or tapered bores.
