2. The rotation speed is high, the ceramic ball has oil-free self-lubricating performance, and the friction coefficient of the ceramic ball is small, so the rotation speed of the ceramic ball bearing is more than 1.5 times.
3. Long service life, ceramic balls can be used without any grease, and the service life is 2-3 times that of ordinary bearings.
4. Insulation. Bearings made of ceramic balls can insulate the inner and outer rings of the bearing.
5. Application: bicycles, aerospace applications, reactors, medical equipment.
