Rulon Bearings

(Viewing data as-entered. Click here to return)
Saint-Gobain Rulon® 1045 Bearing/Seal PTFE
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)

Material Notes: Rulon® 1045 is a dull gold material that has an excellent ability to elongate in a flip seal application. Coupled with excellent frictional characteristics, it offers the added benefit of energy savings, as well as increased sealing efficiency.

This material is also resistant to many harsh chemicals found in the application environments where it is typically used. It is also compatible with most commercially available lubricants for additional reduction in friction. Its low deformation properties allow it to be effective as a bearing or sliding surface.

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
