[Application Features] SF-2S non-oil lubricated bearings, SF-2 is an improved product, with copper back as the substrate, middle sintering spherical bronze powder, the surface rolling acetal resin and containing lipophilic fibers and special lubricants The polymer material. Same products abroad for the DS bearing, adapt work under normal temperature conditions dry friction and less oily occasions, with a low coefficient of friction, wear resistance, oil-free advantages. [Application] The product has been used in a swinging motion, easy to wear, corrosive applications, such as volume field, bulldozers, printing machines, shearers and cranes, aerial work traffic and other occasions. The main parameters maximum load pressure: 70N / mm2 friction coefficient μ: 0.04 ~ 0.20 Temperature range: -40 ℃ ~ 130 ℃ Maximum sliding speed: 5m / s to allow the maximum PV value: 25N / mm2.m / s
