[Application Features] SF-1F flanging self-lubricating bearings, Steel substrate, middle sintering spherical bronze powder, a mixture of surface rolling polytetrafluoroethylene (PTFE) and lead, rolling a sliding bearing. 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] products 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 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 allowed maximum PV value (oil): 50N / mm2.m / s
