[Application Features] SF-1S stainless steel corrosion-resistant bearings, as the base is stainless steel, sintered corrosion resistant alloy powder, the surface rolling polytetrafluoroethylene-based low-friction material, after rolling forming a kind of very effective corrosion resistant materials. It has oil, acid and alkali resistance, water resistance and wear characteristics, PTFE material surface is lead. [Application] in the food and beverage machinery, moderately acid flow valve chemical, pharmaceutical machinery, printing machinery, chemical machinery, marine industry corrosion sliding parts most suitable for use. The main parameters Load capacity: 140N / mm 2 friction coefficient μ: 0.04 ~ 0.20 Temperature range: -195 ℃ ~ 280 ℃ Highest sliding velocity: 2.5m / s to allow the maximum PV value (dry): 3.6N / mm2. m / s to allow the maximum PV value (oil): 50N / mm2.m / s
