Back to Rulon®

Rulon® LR is a maroon colored material best known for its versatile design properties. This widely used Rulon® formulation and has a long reputation for high wear resistance, low friction, good electrical properties, and chemical inertness.  Rulon® LR makes a great sleeve, flange, or thrust bearing.  It can also be bonded to nearly any surface to provide wear resistance and reduce friction due to the continuous non-lubricated properties.

Notable Material Features

  • High compression strength
  • Low coefficient of friction
  • Excellent abrasion and corrosion resistance while running without lubrication
