GGB HSG Fiber reinforced composite plain bearings with PTFE

GGB HSG Cylindrical bushes

HSG High-Load Fiber Reinforced Composite PTFE Bearings

CHARACTERISTICS

  • Self-lubricating plain bearing material
  • High static load capacity (twice as much as standard GAR-MAX® bearings)
  • Excellent shock and misalignment resistance
  • Excellent contamination resistance
  • Very good friction and wear properties
  • Good chemical resistance

availability

Bearing forms available in standard dimensions
  • Plain cylindrical bushes
Bearing forms made to order: cylindrical bushes with non-standard lengths and wall thickness, flanged bearings, hexagonal and square bores, liner on outer diameter, customized bearing designs

STRUCTURE AND COMPOSITION

Fiber and Epoxy Resin Composite Bearing Material 

Continuously wound PTFE and high-strength fibers encapsulated in an internally lubricated, high temperature filled epoxy resin sliding layer + continuous wound fiberglass encapsulated in a high temperature epoxy resin, designed for high load capacity
