1. Ceramic Hybrid Bearings

 

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)

 

Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubrication and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds.

 

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.

 

2. Full Ceramic Bearings

 

Full Ceramic Bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.

 

Full Ceramic Bearings are usually made of following materials:

 

Silicon Nitride (SiN4)

Alumina Oxide (Al2O3)

Zirconia Oxide (ZrO2)

Silicon Carbide (SiC)

 

Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubrication and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds.

 

Full Ceramic Bearing Benefits

 

Will not corrode or rust

2/3 the weight of steel

Resistant to resist acids, alkali, blood, salt and water

Extremely low coefficient of friction and thermal expansion

Lower friction results in less energy consumed

Operating Temperature from as low as (-85°C) up to (+ 900°C)

 

Full Ceramic Bearing Applications

 

Full Ceramic bearings are used in specialty applications like chemical baths, vacuum environments, semiconductor manufacturing, food processing industries, radiotherapy, MRI, patient positioning systems and more. Any extreme environment that requires non-corrosive, non-conductive or non-magnetic bearings is ideal for full ceramic bearings.
