Ultracomp Grades Decoded

By Dave Biering on 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).

Ultracomp Conveyor Bearings Roll Along for the “Toy of the Century”

By Dave Biering on September 11, 2014

Ultracomp Conveyor Bearings Roll Along for the “Toy of the Century”Agriculture, railroad, construction and other heavy-duty applications are primary areas for Ultracomp bearings – but did you know that the material also helps the “Toy of the Century” meet their holiday production goals? Here’s how:

As the holiday gift-giving season revs into high gear, toy manufacturers look for every advantage to meet increased demand. After all, a breakdown on the production line can lead not only to costly repairs, but potentially missed shipments to toy retailers worldwide. 

When the maker of plastic building blocks approached us to replace their failing metal bearings on their conveyor systems, Ultracomp was the natural choice. Our client described how the blocks begin as granulated plastic and are sent to the high-temperature molding machine. Once molded, the blocks roll along to packaging where they are sorted by shape, color and size and packaged into specialized kits. The metal bearings our client had installed on the conveyors would seize up from the dust generated in molding. The dust adhered to the grease that was applied to the metal conveyor units. The grease also dripped onto the formed parts, which caused a serious quality control challenge.

Since switching to grease-fee Ultracomp bearings, our partner reports the conveyor belts resist plastic dust to run more efficiently and deliver better quality products. And unlike metal bearings, Ultracomp bearings resist friction and vibration and excel against the stainless components of the production line. 

We might even say that Ultracomp delivers the performance of the century to the “Toy of the Century!”

Q&A: Which material do you recommend for small construction equipment? Our cast nylon bearings are not lasting as long as we’d like.

By Dave Biering on April 3, 2012

This question was posed to us from a manufacturer of small excavators, the kind you often see in the consumer rental market.  Cast nylon is a good material for farming and construction, but with some drawbacks when it comes to moisture absorption and UV stability.  Depending on where you use them, nylon is good for cable sheaves, but for pivot points, we recommend these materials for top performance.

Plane bearings for a wet environment

By Dave Biering on September 22, 2010

Over the summer — at the height of boating season — I was asked how to choose the right bearing for use in a wet environment.  As a whole, plastics do not do well in wet applications; most traditional polymers tend to absorb moisture and saturation. Nylon materials, for instance, are susceptible to humidity and swelling issues.  Even those polymers that do well in water can usually withstand freshwater only, not saltwater. 

So what are your bearing choices for a wet environment application?  Polyesters and Acetron materials hold up well.  And our marine clients have done extremely well with Ultracomp for their rudder bearings, since they are durable and excel in linear, oscillating and rotary applications.  Our CJ product line is another good choice, since they remain dimensionally stable in liquid.  No matter what material you choose, we recommend that you avoid graphite, because it gives a cathodic charge in saltwater.

Very few PTFE-based materials excel in water, but we can help you find the right one for you freshwater, saltwater, DI, or chemical blend submerged applications.
