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.
Rulon® J is a specific type of Rulon®, a PTFE (polytetrafluoroethylene)-based composite material, known for its gold color, exceptionally low coefficient of friction, and ability to perform well against soft mating surfaces like stainless steel, aluminum, and brass. It features a unique filler that enhances temperature stability and provides superior wear and friction properties, making it ideal for high-speed, low-load applications where low friction and self-lubrication are crucial.
