  • What's features and advantages of self aligning ball ...

    Self-Aligning Ball Bearings:In a self-aligning bearing, the inner ring has two raceways and the outer ring has a single spherical raceway with its centre of curvature coincident with the bearing axis. This allows the axis of the inner ring, balls and cage to deflect around the bearing centre to automatically correct misalignment caused by housing and shaft machining or installation error.
