 1.Hybrid ceramic ball bearing 

Ceramic hybrid bearings have steel races and ceramic balls. Ceramic balls are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually frictionless and capable of spinning faster than steel balls.

2.Specifications of  hybrid ceramic bearing 6902 2rs

3.Temperature Range

Standard bearings reduce their hardness and fatigue lives when they are continuously used in high operating temperatures.  Silicon nitride (Si₃N₄) is suitable to be used in high temperature environments without loss of its hardness and life endurance.  With its rings made of special steel for high temperatures, hybrid bearings with ceramic balls are successfully used in the field of high temperatures.

1.Extreme wear resistance

Silicon Nitride balls are 2.3 times harder than hardened steel

2.Reduced need for lubrication

CeramicSpeed 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.
