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.
According to ISO standard,the CA cage design can be replace the CC cage if the basic conditions (load rating,limiting speed,Operation Temperature,noise vibration) coincide with design structure limit.in fact the spherical roller bearing service life,in addition to bearing own quality assurance,the bearing type choice and bearing installation,use,maintenance is also affect the performance of the spherical roller bearing.
As one of China bearing manufacturer.XRB spherical roller bearing focus on learned high technology and knowledge from the worldwide spherical roller bearing manufacturer from 1998,and until now,XRB can produce the full-line sealed spherical roller bearing,bearing for vibrating screen equipment,warmly hope the customers from worldwide contact with XRB for sealed spherical roller bearing.
