The Advantages of Hybrid Ceramic Bearing:

1. Anti-rust, strong anti-corrosion ability: The inner and outer rings and cages of hybrid ceramic bearings are made of stainless steel, which makes them have excellent rust and corrosion resistance.

2. Low-friction, high-speed: The friction coefficient between the Si3N4 ceramic ball and the stainless steel inner and outer rings of the hybrid ceramic bearing is very small so that the hybrid ceramic bearing has a very high speed without grease. The speed of hybrid bearings is 1.5 times that of ordinary bearings.

3. Long-life, maintenance-free: The special material makes the life of hybrid ceramic bearings 2-3 times that of ordinary bearings. Hybrid bearings usually adopt dry friction operation mode, and do not need to add lubricating grease regularly.

4. High temperature resistance, ceramic ball thermal expansion coefficient is small, in the high temperature environment will not cause the bearing ball to expand due to temperature, which greatly improves the use temperature of the entire bearing, the temperature of ordinary bearings is about 160 degrees, ceramic ball Can reach more than 220 degrees.
