Rulon Bearings

Saint-Gobain Rulon® AMR Bearing/Seal PTFE
Categories: Polymer; Thermoplastic

Material Notes: Same base material as Rulon AR but Rulon AMR contains a percentage of molybdenum disulfide for increased wear resistance and lower coefficient of friction. Typically used as a seal or gasket, Rulon AMR is specified in many military and commercial applications for hydraulic and pneumatic controls.

Information provided by distributor TriStar Plastics Corp.
