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
