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.

The rollaway of outside race is in shape of sphere.                                   

It has self aligning and it can make up for the error which from different angles. But its opposite gradient between outside and inside race is less than 3 degrees. The structure principle and the character of the bearing are the same with self aligning ball bearing. Under the condition of permissible volume of load and permissible speed of rotation, they can interchange.


Self aligning roller bearings apply to precise instrument, the electrical appliance of low noise, automobile, motorbike and other machineries. It is used the most widely in mechanical industry.

Competitive Advantage:
1.  Quality level: reach the same level as the Japanese and European bearings
2.  Tolerance level: ABEC-1 (P0), ABEC-3 (P6)
3.  Less coefficient of friction
4.  High limiting speed
5.  Large size range 
6.  variations of structure
