Spherical roller bearings are principally provided with two rows of symmetrical spherical rollers and a common sphere raceway in the out ring, the two inner ring raceways are included at an angle to the bearing axial. The bearings have good self-aligning ability and can operate when the shaft deflection under load or the shaftmisaligningment in mounting, and their permissible aligning angle is 1 to 2.5 degree. This type of bearings has heavy load, carrying capacity and anti-impact ability, in addition to radial loads, they alsocan carry axial loads. In the two directions, In general, this type of bearings permit a low limiting speed.

Quality control:
1. Material
2. Physical and chemical examination-controls the metallurgical constituents of the material
3. Spectroanalysis instrument
4. Eccentric casting of brass cage
5. Heat treatment-improves the life of the product
6. Foundry master and three coordinate measuring machine-ensures the products precision
