P6 Grade Spherical Roller Bearing for Electric Machinery

Spherical roller bearings are inherently self-aligning and very robust. They have two rows of rollers which make the bearings able to carry heavy loads. Our TVB brand spherical roller bearings mainly includes CC, CA, CAE, MB and E type. TVB can provide a wide range of sizes of several ISO Dimension Series and also includes special designs. Special bearings can also be customized as required based on the standard bearings.

1.Internal Structure and Retainer Material Variation 

 C:        Symmetrical roller, Stamped Steel retainer

 CA:      Symmetrical roller, one-pice brass cage

 CTN1:  Symmetrical roller,  nylon cage

 E:  Third generation design. improved stress distribution; offer much longer service life than normal designs

 Q:         Bronze cage

 MB:      Symmetrical roller,Two-pice brass cage

 EM:      Symmetrical roller, Special alloy Integral cage.

2.External form chnage
