High Perfomance Ceramic Hybrid Bearings with Steel Races and Ceramic Balls
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.
