TriStar TriSteel AT Metal Backed PTFE Bearing System
Categories: Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM); Fluoropolymer; Polytetrafluoroethylene (PTFE)

Material Notes: Ultraflon 601T (AT) POM bronze with PTFE, lined metal back bearing system, high PV, self lube, high speed. This liner will run with zero lubrication required. Most commonly used in clip bearings, lift and tilt on medium speed and load applications. Liner thickness allows for secondary machining to accommodate misalignment or minor ID tolerance corrections.

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
