high speed Si3N4 ceramic balls Hybrid ceramic bearings 6000 6001 6002

 ceramic bearings features:

1.Extreme wear resistance
Silicon Nitride balls are 2.3 times harder than hardened steel

2.Reduced need for lubrication
Ceramic Speed balls are 4 times smoother than steel. The friction coefficient of CeramicSpeed balls against steel is 0.2, whereas the friction coefficient of steel against steel is 0.8.

3.Low Friction
The ceramic balls are rounder, lighter and smoother, reducing friction and energy loss in comparison to steel balls. Optimising other components in the bearing reduces friction even further – without reducing the lifetime.

4.Increased stiffness and reduced vibration
The ceramic balls have an extremely low coefficient of expansion – only a quarter that of steel balls, and are both rounder and smoother; this means that the bearing is more precise, with less vibration. At the same time the ceramic balls polish the races, so they become smoother over time.
