Rulon J Rulon LR

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 dull gold in color and provides one of the lowest coefficient of friction of all Rulons, and provides good wear and abrasion resistance. Because this grade is "all plastic", it can be run on non-ferrous and non-metallic mating surfaces such as 316 Stainless, brass, and other plastics. It is used in both bearing and seal applications, but is generally not suitable for use in alkaline or oxidizing acid solutions. This is the best Rulon grade for aluminum and soft mating surfaces.

Rulon ® J offers a very low coefficient of friction vs. other filled PTFE grades.
