Spherical Roller Bearing Basic type

Most of the Spherical roller bearings in OD less than 320mm are the structure reinforcing E series bearings. Their difference from other bearings is that their inner ring has no center rib, therefore their roller is longer. The rated load of these E series Spherical roller bearings is obviously more than other common Spherical roller bearing.
Spherical roller bearings have the cylindrical bore or tapered bore.
The Spherical roller bearing with tapered bore is mounted on the shaft through adapter sleeve or withdrawal sleeve

Spherical Roller Bearings, the dimensional series are:

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.

CCFeatures 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 appliexcavatorions and long service life.
