Spherical roller bearing cage CA & CC

Cage is one of the four elements of spherical roller bearing,it affects the performance and service life of the spherical roller bearing directly,what is the most important is the material,the material of the cage should have high mechanical strength,good wear resistance,the impact of fluctuating load and excellent dimensional stability and the other characteristics. for double row spherical roller bearing,we usually used the materials:Quality carbon structural steel strip,steel plate,High tensile strength solid machined brass cage,Plastic cage, etc.

 

the CA cage design of spherical roller bearing was developed in 1950s,the spherical roller bearing CA have solid machined cage and enhanced Symmetrical rollers,compared with CC structure,CA design adopted high tensile strength brass cage,it has a certain self-lubricating properties,and allow a certain degree of plastic deformation,under the current restrictions mold process conditions,CA cage its better than CC design in the case of low noise requirements. meanwhile,CA cage take more internal space of spherical roller bearing,so the dimension of the elements and quantity would be effected,thereby reducing the possibility of further increase its radial load capacity.
