The Self-aligning ball bearings

Self aligning ball bearings are suitable for applications where misalignment can arise from errors in mounting or shaft deflection. The steel balls, cage, and inner ring can rotate freely at a certain angle, as it is stated that the bearings have self-aligning features. Accordingly, misalignment of the bearing shaft due to the machining and installation of the shaft and housing will be automatically adjusted.

With two structures of bore cylindrical or tapered and retainers made of steel sheet or synthetic resins, the characteristic of their spherically formed outer ring raceways allowing for misalignment within 3 degree deflection between inner ring and outer ring, so as to compensate concentricity and deflection errors.

Self aligning ball bearings are widely used in mining machinery, power machinery, heavy machinery and textile machinery etc.
