TriStar Ultracomp UC-300 Composite Bearing
Categories: Polymer; Thermoplastic

Material Notes: Ultracomp UC-300 - Similar in construction to UC-200. Containing special fillers that reduce its coefficient of friction, UC-300 is designed to handle higher rotational and linear speeds.

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.

Vendors: TriStar Plastics Corp. provides engineering, custom fabrication and manufacturing of high-performance plastics and self-lubricating bearing materials, such as Rulon, PEEK, Torlon, CJ Composites and Ultracomp. Capabilities include component design, material selection, prototype and production, manufacturing and surface modification. Call (800) TRI-STAR (800) 874-7827 or visit or www.TStar.com
