Oiles Drymet LF Polytetrafluoroethylene plastic multi-layer bearings with back metals Feature ●Serviceable without the need for lubrication. Thin and lightweight for compact design. ●Demonstrate low coefficient of friction and superior load performances in high-load, low-speed conditions. ●Usable at the high PV values even in the middle- and high-speed zones when lubricated. ●Usable in wide temperature ranges from low to high temperatures. Has superior chemical resistance. ●Features superior dimensional stability, mechanical strength, and thermal conductivity. ●The standard products and plate materials are available in various sizes.
