Characteristics

  • Powder metallurgical bearing material consisting of a solid lubricant homogeneously distributed in a metallic matrix
  • Self-lubricating and maintenance-free by forming a solid lubricant film during the relative motion
  • Excellent high-temperature resistance
  • High wear resistance
  • Low-friction properties
  • Resistant to corrosive environments
  • High load capacity
  • High dimensional precision
  • No requirement to operate against high cost special counter surface materials with specific hardness requirements, a standard stainless steel counter surface is appropriate

APPLICATIONS

Automotive - EGR valves, exhaust heat recovery systems (EHRS), exhaust throttle valves, exhaust brakes, turbocharger wastegate valves

Industrial - Industrial & domestic ovens and furnaces, natural gas/petrochemical valves, exhaust or smoke flaps, high temperature valves, heavy-duty engines, applications with elevated temperatures & corrosion risk, industrial processing plant applications, gas and steam turbines

Aerospace - Engine turbo fans, engine guide vanes, engine pneumatic-bleed valves

AVAILABILITY

Bearing forms made to order: According to customer design/drawing. Regardless of shape size or material, we can customize your shape. High volume production is feasible.
