ZWZ Spherical Roller Bearing 22207 With Brass Cage           

 What is spherical roller bearing?

Self-aligning roller bearing is between in a two roll way inner ring and outer raceway for spherical , assembly with drum roller bearing.

Spherical roller bearing profile:

It's have two columns roller,main bear radial load, at the same time also can bear any direction axial load.Have high radial load capacity. Especially suitable for heavy duty or vibration work under load,but can't bear pure axial load. This kind of bearing's outer ring raceway is spherical shape, so its self-aligning performance is good, can compensate for the coaxiality error.

spherical roller bearings 22207 Designs and Structures
CTN1: Nylon retainer.
C: Stamped steel retainer and strengthened symmetric rollers; offers considerably higher load ratings than conventional designs for a broad range of applications and long service life. 
CA: Alternative design of C design; Precision-machined one-piece brass retainer and strengthened symmetric rollers; used to exchange with C design, especially for large size. 
MB: Two-piece precision-machined brass retainer and strengthened symmetric rollers; equivalent to C design in load capacity.
CC: steel cage, replace traditionalbrass cage.
E: Third generation design. 
The bearing contact is completely optimized and has improved stress distribution; offer much longer service life than normal designs.
