Spherical roller bearing with chrome steel material is very common in our bearing industry,and this kind of material bearing used brass cage or pressed cage and also can be nylon cage,just like CA(One-piece solid cage),CC(two piece press steel cage),MB(Two piece brass cage),TVPB( nylon cage),and with the spherical rollers ,these design of spherical roller bearing is the widely used in many applications.
 
With the development of industry and the improvement of the market,some application need the spherical roller bearing have the anti corrosion and lower noise ,just like the Medical Devices, Cryogenic Engineering,Optical Instruments,food process machine,so stainless steel spherical roller bearing appeared,this kind of bearing adopted AISI SUS440C(9Cr180Mo) stainless steel material,the cage is AISI304 stainless steel,and working with the high quality lubrication oil or grease,it can working high or low temperature than the chrome steel spherical roller bearing.
 
Theoretically speaking the spherical roller bearing can be made of ceramic material,but its very high cost and less market demand,so we don't talk about this kind of matarial about spherical roller bearing.
 
The raceway of Spherical roller bearing have the radian feature,and also the big and wide size ,so its very difficult in processing then the other kinds of bearings,XRB will supply  Optimization Configuration for your application,for example the selection of size,the cage for the the working condition,the lubrication,the seals and more details,we alway give our valuable customers the best solution of the bearing.
