HOME / PEEK GRADES / PK-BRG
bearing grade PEEK for bushings; seals & wear parts

PK-BRG — Bearing-Grade PEEK (CF / Graphite / PTFE)

Tribological PEEK compound with carbon fiber, graphite and PTFE, engineered for dry or marginally lubricated sliding and bearing applications.

Key Features

  • Low friction and wear; dry-running capable
  • High PV limit for continuous sliding
  • Self-lubricating — no external grease
  • Excellent chemical and temperature resistance

Applications

Bearing bushes, thrust washers, seal rings, compressor piston rings, sliding elements in pumps and textile machinery.
