[Application Features] SF-2Y Lead-free boundary lubrication bearing is improved on the basis of the SF-2. Its performance and SF-2 the same, but the surface does not contain lead, use of the area can be extended to the field of environmental protection requirements. [Application] The product has been applied to imports of textile equipment, swing piston pump parts, auto operating parts like load, speed, grease lubrication occasions. The main parameters maximum load pressure: 70N / mm2 friction coefficient μ: 0.05 ~ 0.25 Temperature range: -40 ℃ ~ 130 ℃ Highest sliding velocity: 2.5m / s to allow the maximum PV value: 22N / mm2.m / s
