Rulon® J | Lowest Coefficient of Friction

Rulon J

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.
