[Application Features] DU composite bushings / roll bushes, Steel substrate, middle sintering spherical bronze powder, a mixture bearing surface rolling polytetrafluoroethylene (PTFE) and lead, rolled into exports products are generally tin-plated (silver). It has a low coefficient of friction, wear resistance, corrosion resistance, no oil lubrication characteristics. Use the product can reduce cost, reduce mechanical volume, avoiding the phenomenon of bite-axis and reduce mechanical noise. [Application] The factory production of composite bearings, composite bushings have been widely used in various mechanical sliding parts, such as printing presses, lifts, textile machines, tobacco machines, fitness equipment, pallet trucks, micro-motors, solenoid valves, automobile, motorcycle and forestry machinery. The main parameters Load capacity: 140N / mm2 non-oil bearing friction coefficient μ: 0.04 ~ 0.20 Temperature range: -195 ℃ ~ 280 ℃ Maximum sliding speed: 5m / s to allow the maximum PV value (dry): 3.6N / mm2 .m / s to allow the maximum PV value (oil): 50N / mm2.m / s
