Oiles Fiberflon TR Multi-layer polytetrafluoroethylene plastic bearings Feature Serviceable without the need for lubrication. Has superior wear resistance. Demonstrates the low coefficient of friction of the PTFE plastic as is. Offers superior performance under high-load, low-speed conditions. The sliding surface is made of cross-woven fabric hardened firmly with plastic to improve cold flow, disadvantage of PTFE, remarkably. Has superior heat, cold and chemical resistance. Backing materials are selectable according to applications. May be used in water and seawater. Service range Lubrication condition Allowable max.
