Ultracomp Grades Decoded

May 15, 2018

Ultracomp Grades Decoded

Ultracomp is a family of laminate wound bearing materials with migratory lubricants added to the resin system. All Ultracomp bearing materials are high load, low speed materials designed to operate in extreme conditions without additional lubrication.

Most competitors use a wet-wind system, but Ultracomp uses a prepregnated fabric system. Prepreg is a cleaner and more efficient manufacturing system, as wet-wind processing results in a loss of properties; in other words, the wet-wind process reduces the performance of the resulting bearing.

Ultracomp is constructed of synthetic resins and reinforcing fibers and each variant uses one of three migratory lubricants:

1. Graphite


3. MOS2

Here’s a breakdown of the core Ultracomp products


  • Description: Designed for high load, high impact, slow speed, and vibratory applications. UC200 has excellent abrasion resistance, does not require lubrication, and has extremely low moisture absorption.
  • Resin and Lubricant: Bearing Grade Polyester / Graphite Composite
  • Applications: Oscillating and sliding applications.



  • Description: Similar in construction to UC200, with PTFE lubricant added to the resin matrix to reduce its coefficient of friction.
  • Resin and Lubricant: Bearing Grade Polyester / PTFE Composite
  • Applications: Rotary or linear applications



  • Description: Similar in construction to UC200 with moly lubricant
  • Resin and Lubricant: Bearing Grade Polyester / MOS2 Composite
  • Applications: Slow rotary, salt water, and dry oscillation applications



  • Description: Unique interwoven laminate using PTFE, polyester fibers, and graphite lubricant.
  • Resin and Lubricant: Bearing Grade Blended Fiber / Graphite Composite
  • Applications: full rotary applications where self-lubricated low friction and long wear is required.

Other Varieties

There are a number of other varieties of Ultracomp, designed to be used in specialized situations. An example of this is UC200FR which has similar performance characteristics to UC200 but utilizes a special resin fabric which makes it fire resistant.  Another variation is UC300AR, which is similar to UC300 but is manufactured with a resin with a higher temperature rating which allows it to operate at a peak temp of 340°F (versus 325°F for regular UC300).
