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

Double Sealed Self Aligning Ball Bearing

Spherical Roller Bearing
With the same center as the bearing, the spherically formed outer ring raceway can make selfalignment.Their rolling elements linearly come into contact with the raceways of inner ring and outer ring .The bearings can take greatly radial load , suitable for heavy machinery used in mining,metallurgical,paper-making and nstructing,etc.,Industry
