Thrust ball bearing cage

Thrust ball bearing can not bear radial load, but it can bear a small axial load. The limit speed is low. It is widely used in compressor, vertical pump, low speed reducer and other fields.

Needle bearing cage

It can bear large radial load and occupies little space, which is conducive to the compact design of machinery. This kind of bearing adopts engineering plastic retainer, copper retainer and steel plate stamping and welding retainer.
