Thermoset vs Thermoplastic Materials: Bearings and Other Applications
Thermoset and Thermoplastic materials have similar names, but they have very different properties....
TriStar offers a wide range of bearing materials that are ideal for non-lubricated, high-load applications.
TriStar is the exclusive partner of Saint Gobain for Rulon materials in North America.
Our capabilities include component design, material selection, prototype, production, and manufacturing.
Since 1982 we have been combining the skills of TriStar’s engineering team, our extensive product line, and our deep understanding of a broad range of industries to bring you solutions to your most challenging engineering needs.

One of the original Rulon compounds, Rulon J is a reinforced material that combines the best in wear and friction properties with superior value. Gold colored, Rulon J uses a unique filler that adds temperature stability for enhanced wear. It is considered a “shaft-friendly” compound and operates well against soft mating surfaces such as 316 stainless steel, aluminum, mild steel, brass and other plastics.
Rulon J has a PV rating of 7500; which is one of the lowest of all PTFE-reinforced materials. It is ideally suited for start/stop applications where stick/slip must be eliminated. It is not recommended in steam or otherwise wet environments.
When you want low maintenance, self-lubrication, and the lowest coefficient of friction of any PTFE blend, consider Rulon J.
