Graphite Plugged Bronze Bushings / Bearings

Graphite Plugged Bushings are a complete line of Self-Lubricating Bushings that excel whenever standard lubrication is impractical, including heavy load, high temperature applications. They are manufactured from a variety of Bronze Alloys, including: C95400 Aluminum Bronze, C93200 Bearing Bronze and C86300 Manganese Bronze.

  • Self Lubricated when standard lubrication is impractical
  • Performs well under various loads, types and speed operations
  • Resists corrosive and hostile environments
  • Excellent performance in medium to high temperatures up to 600 F
  • Compatible with most viscous lubricants & Oil and Grease applications

Our standard line features over 1,000 sizes that are carried in stock.
