HPMB®

High Precision Fiber Reinforced Composite Bearing
GGB HPMB self-lubricating filament wound cylindrical bushings
GGB HPMB self-lubricating high precision fibe reinforced composite bearings

Characteristics

  • Machinable inner and outer diameters for superior application precision, circularity and cylindricity tolerances
  • Pre-machined high precision HPMB bearings available for immediate installation
  • High precision through easy single point machining of the bearing liner, on-site prior to installation
  • Superior precision achieved with post-installation (inner diameter tolerance IT7 attainable) single point machining of the bearing liner
  • High load capacity
  • Excellent shock and edge loading capacity
  • Low friction with negligible stick-slip
  • Low wear rate for extended bearing life
  • Excellent corrosion resistance
  • Dimensionally stable - very low water absorption, low swelling
  • Environmentally friendly grease-free operation
AVAILABILITY

Bearing forms made to order: finished cylindrical bushings, pre-machined cylindrical bushings, flanged cylindrical bushings (subject to design review)

Structure & Composition

 

  • Fiber and Epoxy Resin Composite Material 
  • Machinable liner composed of continuously wound PTFE and high-strength self-lubricating fibers and high temperature epoxy resin + continuous wound fiberglass backing encapsulated in a high temperature epoxy resin
