High Perfomance Ceramic Hybrid Bearings with Steel Races and Ceramic Balls

ceramic bearing.jpg

 

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.

 

Ceramic Balls are usually made of following materials:

 

Silicon Nitride (SiN4)

Alumina Oxide (Al2O3)

Zirconia Oxide (ZrO2)

Silicon Carbide (SiC)

 

Ceramic Hybrid Bearing Benefits

 

High loads, high speeds and extreme temperatures are factors

Increased bearing life and decreased down time

Minimal need for lubrication

No cold welding between ceramic balls and races

Multi-purpose use in variety of machines and different production lines

High efficiency, low weight and small size

 

Ceramic Hybrid Bearing Applications

 

Ceramic hybrid bearings are widely used in electric motors, aerospace applications, performance racing vehicles, laboratory equipment, under water applications and more. Any application that requires higher speeds, lower friction and longer life are ideal for ceramic hybrid bearings.
