Spherical Roller Bearings Designs

CA---The alternative design of the second generation, these bearings feature a precision-machined brass cage and strengthened symmetric roller and are equivalent to CC design in load ratings. They are used to exchange with C design, particularly for large size.

MB---Feature a two piece precision-machined brass cage. These bearings incorporate strengthened symmetric rollers, and are equivalent to CC design in load capacity.

CC---Features a stamped steel cage and strengthened symmetric roller. As a second generation design, these bearing designs are optimized to offer considerably higher load ratings than conventional designs for a broad range of applications and long service life.

Spherical roller bearings---CA/MB/CC
