Ceramic ball bearing especially 1205k have the following performance as low density, high strength, low friction coefficient, electrical and magnetism resistance, wear resistance, well rigidity, lubrication and maintenance free when working, it's the best choice for rollers (inner ring and outer ring are made by metal) of the hybrid construction which are used in high-speed, high accuracy and long life environments.
Compared with steel ball, 1205k ball has following advantages:
- 23%lighter than steel ball, which means less centrifugal force and less friction on the groove during high speed and acceleration.
- Smaller fiction coefficient, more freely rolling.
- Can be used at higher temperature up to 750°C
- Never rust, and can roll with out lubrication.
- More corrosion resistant than steel
- No metal contamination.
- Non-magnetic
- Electric isolation
