Miniature deep groove ball bearing:
There are many types of miniature deep groove ball bearings, including the metric 68 series, 69 series, 60 series, etc., as well as the British R series. In addition, different types of with ZZ steel dust cover, RS rubber seal ring and flange flange can be selected according to requirements.
The main materials are carbon steel, bearing steel, stainless steel, plastic, ceramic and so on. The choice of these materials directly affects the performance and service life of bearings. For example, bearing steel has good comprehensive mechanical properties and wear resistance, stainless steel is suitable for wet or corrosive environments, and ceramic materials are suitable for high temperature, high speed and high load occasions.
