Ultracomp Composite bearings are made using different migratory lubricants. PTFE, Graphite and MOS2 are the traditional lubricants used in these high load, low speed bearings. Historically, MOS2 has been the lubricant of choice in marine environments because of the compatibility of the moly with mating hardware in salt exposure. Graphite would act as a cathodic agent against stainless or other metals when exposed to salt air, salt fog or salt water. Tri Star recommends UC300 with PTFE lubricant as a more universally acceptable material. For dry or wet applications, the PTFE lubricant is an effective agent for low friction lubrication, is compatible with soft mating hardware like aluminum and stainless and has no corrosive effect in the salt environment. Let us know if you have issues with corrosion in your marine bearing applications. We have a solution!

Composite self lubricating bearings take advantage of superior strength from filament or laminate wound structure. Add to that a variety of lubricating media like PTFE, MOS2, Graphite and combine with abrasion resistant, high strength woven liners and you have the makings of super bearings! Composite bearings are primarily applied to high load, low speed applications however new liner materials allow for speeds up to 500 feet per minute without lubrication. Another unique quality of composite bearings is they love to be under water. Excellent materials for marine applications under water, deck side and dock side.
