1. Ceramic Ball Bearing description:

1) Bearing configuration: inside and outside the circle ceramic ball bearing steel/

stainless steel + + PA66 + 2 rs/ZZ/stainless steel retainer
2) Ceramic ball bearing advantages: high heat resistance, high speed, long life, insulation.

2.The classification of ceramic ball bearing
According to material: ceramic bearings can be divided into zirconium oxide ceramic bearings,

silicon nitride ceramic bearings, bearing composite ceramic materials.
According to the structure points: ceramic bearings can be divided into: zirconia with retainer,

silicon nitride ceramic bearing belt retainer ceramic bearing, compound bearing with retainer ceramics.

3.Bearing application:
Ceramic ball bearing is widely used in all kinds of high precision, high speed machine tools, automobiles, car,

subway, electric machinery, aircraft engine, oil chemical machinery, metallurgical machinery and other fields
