Product Description

With the development of modern machinery, the ordinary steel ball bearings has been far from meeting demands on special requirement such as high temperature, low temperature, high speed,high corrosion etc.
Ceramic ball bearings with higher performance will be the best choice. Runstar Bearing supply ceramic bearing with Zirconia(ZRO2) and Silicon nitride (Si3N4) for choice.

The advantages of ceramic ball bearing are showing as followings.

1. High rotating speed
2. Long Service life
3. Self-lubrication
4. Corrosion-resistant
5. High hardness
6. Low friction torque
7. Wear-resistant
8. Lightweight
9. Nonmagnetic

Field of Application

1. High-speed rotation field
2. Aviation and airspace fields
3. The main shaft of machine tools
4. Chemical machinery, food industry and marine industry
5. High vacuum field
6. Strong magnetic environment
7. Sewage treatment equipment
8. Roller skates, model airplane

Usually,the material of cage for miniature ceramic ball bearings with the inner diameter less than 7mm is PEEK,it is crown, the material of cage for bigger size of bearing is PTFE, it is white.
