TriStar Ultracomp UC-400 Composite Bearing
Categories: Polymer; Thermoplastic

Material Notes: Ultracomp UC-400 - Designed for high loads, low speeds, impact and vibration applications. UC-400 has a MOS2 additive for salt water applications where cathodic reactions could occur. Excellent dry wear properties in slow rotary or reciprocating bearings.

This family of composite materials offers the combination of high compressive strength, low coefficient of friction, and excellent abrasion and corrosion resistance while running without lubrication. They are used in bearing and seal applications from temperature extremes of cryogenic to over 360°F with and without additional lubricants.

Ultracomp Bearing Grade Composite: Laminates composed of synthetic fabrics impregnated by thermosetting resins and solid lubricant fillers. Material is available in tubes and sheets. Ideally suited for non-lubricated ultra high-load/low-speed applications that require a low coefficient of friction. Operates well in demanding and destructive environments. Suitable for use in steam, wet, dry, or vacuum environments. Rc 35 or higher steel mating surface. Markets for Ultracomp Bearing Grade Composite include Agricultural, Appliances, Automotive, Construction, Industrial, and Transportation.
