Hard Surfaces at High Temperatures

     Waukesha Bearings applies ceramic and cermet (ceramic-metallic composite) materials to thrust and journal bearing designs to extend bearing capabilities in applications where traditional materials and polymers fall short.

     The extremely hard surfaces of ceramic/cermet bearings can handle corrosive materials, contaminated lubricant and temperatures beyond the limits of polymers and traditional materials.

Advantages

  • Retain mechanical properties and load carrying capacity over a wide range of temperatures, including extremely cold and hot environments

  • Compatible with very thin hydrodynamic films and low-viscosity lubricants

  • Resistant to most chemicals, including hydrogen sulphide and ammonia

  • Harder than common abrasives, such as sand

  • Prevent bearing damage by crushing abrasive debris in the lubricant
