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
