Needle roller bearing cage can bear large radial load and occupies little space, which is conducive to the compact design of machinery. It is widely used in automobile, household appliances, electric tools, machinery and other fields. This kind of bearing adopts engineering plastic retainer, copper retainer and steel plate stamping and welding retainer.
