Multi-layer polytetrafluoroethylene plastic bearings ^ Free • 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 Condition: in atmosphere, bushing, shaft rotation. Multi-layer polytetrafluoroethylene plastic bearings This product is registered in the New Technology Information System (NETIS) managed by MLIT. Technology name : Solid-lubricant dispersed bearing FIBERFLON OH/Registration No. : KT-130060-VE (for water gates/underwater pumps) • This product can be used in air, water or seawater. • Demonstrates superior wear resistance under micro-motion. • Thanks to the dual structure of the sliding layer and backing material (FRP:glass fiber), this product offers load bearing characteristics equivalent to those of metal bearings. • Easy dimensional setting due to a low swelling rate. • Machining on the inner surface is possible. Service range Condition: in atmosphere, bushing, shaft rotation. The values in parentheses are static bearing pressures, which are the bearing pressures in applications with no motion or very small motion (^0.0017m/s[0.1m/min]). ^The values shown above are typical values, not the standard values. ^The values shown above are typical values, not the standard values.
