Filled graphite bearing from the same API separator after 4 years with excessive wear.

Vespel® CR-6100 Application:

Vespel® CR-6100 can deliver extremely long life and low wear in API separator bearing applications. We have successfully replaced Babbitt/bronze and carbon/graphite based materials with significantly lower wear in this application.

What to do When Applying Vespel CR-6100 or Boulden B-Series to API Separator Bearings:

  • Replace existing bearing materials with engineered composite materials
  • Keep the original design bearing clearance


Benefits of using Vespel CR-6100 or B-Series on API Separator Bearings:

  • Low wear and long life
  • High load-carrying ability
  • Near-zero creep
  • Durable bearings that do not break during assembly or installation
  • Chemical resistance to whatever chemicals might be in the wastewater stream
