Material Notes:
Saint Gobain Rulon® CJ is now produced as a part of the TriStar Plastics Corp. product line under the CJ Bearings trade name.Description: Rulon® is the Saint-Gobain trade name for their family of proprietary PTFE compounds. This family of 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 400°F to over 500°F with and without additional lubricants. A unique property of Rulon® is the absence of stick slip, that is, erratic low-speed motion.FCJ: Identical composition to RULON CJ except the innermost layer is a RULON F tape liner instead of the synthetic fiber/PTFE liner. Ideally suited for non-lubricated moderate-load/high-speed applications that require a low coefficient of friction. Rc 25 and higher steel mating surface. Material has thermal and electrical insulating properties. Suitable for use in wet, dry, or vacuum environments. Markets for FCJ grade include Agricultural, Appliances, Automotive, Construction, Industrial, Transportation.
