Hybrid Bearings

Conventional bearings often fail since they cannot meet all the demands of the various areas of industry they are used in. Hybrid bearings are two-component bearings with the rings made of chrome or stainless steel and the balls made of Si3N4-ceramics. Depending on the requirements various cage materials are used.
 

• Very high temperatures
• Very high rate of revolutions
• Corrosive environment
• Extension of service life
• Electrical insulation
• Quality of emergency operation
• Acceleration
• Dry operation, etc.

• Electrical and welding engineering
• Measuring and control engineering
• Aviation and space technology
• Semiconductor technology
• Pump technology
• Nuclear power plants
• Vacuum
• Micro, etc.

Hybrid bearings are therefore an important and economic alternative to conventional bearings. Consequently, the area of application of many existing conventional bearings can be widely extended leading to lower costs and a considerably improved availability of the equipment.
