22318CA 22318CAK 22318MB 22318MBK spherical roller bearing for gear box

Self-aligning roller bearing is designed to adapt to the circumstance of heavy load. It has two rows of symmetric spherical rollers.the rollers may freely adjust position in the outer spherical raceway,which may compensate the shaft deformation and non-alignment error of bearing seat.

the quantity,length and diameter of roller in self-aligning roller bearing are the max.Value that the structure allows.the close contact between the roller and raceway ensures the uniform stress distribution and enables the high bearing capacity of bearing.

C(J) CC : Two window-type steel cages, flangeless inner ring and guide ring centred on the inner ring

EC(J)  ECC(J) : Two window-type steel cages, flangeless inner ring, guide ring centred on the inner ring and reinforced roller complement  

CA : One-piece machined brass cage, double-pronged, retaining flanges on the inner ring and guide ring centred on the inner ring

ECA  ECAC: Reinforced roller complement, one-piece machined brass cage, double-pronged, retaining flanges on the inner ring, guide ring centred on the inner ring

E : for bearings with a bore diameter d 65 mm:

Two pressed window-type steel cages, flangeless inner ring and guide ring centred on the inner ring

W33: stands for 3 oil holes on the outer ring  groove.
