Spherical roller bearings are designed with double-row raceway inner ring, spherical raceway outer ring and the convex symmetrical rollers. With the same center as the bearings, the spherically formed outer ring raceway can make self alignment, which can adapt the deflection between axis and housing bore.
This kind of bearings can take great radial load, suitable for heavy machines used in paper-making, mining machines, shaker screen machines, rolling mill and so on.
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.
