Vespel CR-6100 gear pump bearings

Previous carbon bearings would fail repeatedly.

Boulden B-Series and Vespel® CR-6100 Applications:

Engineered composite materials can help solve problems with gear pump bearings, particularly in situations where existing materials are brittle or lack chemical resistance to the medium being pumped.

What to do When Applying Vespel CR-6100 or B-Series to Gear Pump Bearings:

  • Replace existing bearing materials with Vespel® CR-6100 or Boulden B-Series
  • Consult with Boulden and the pump OEM to determine the correct clearance

Benefits of Using Composite Materials on Gear Pump Bearings :

  • Low wear and long life
  • High load-carrying ability
  • Near-zero creep
  • Durable material that does not break from mechanical or thermal shocks compared to carbon-based materials
  • Near universal chemical resistance
