SF-1S (self-lubricating bearings) environmentally friendly lead-free stainless steel bearings SF-1S stainless steel corrosion resistant stainless steel bearings as the base, middle corrosion resistant alloy powder sintering, surface rolling with low friction PTFE-based materials and rolled into shape. Is a very effective corrosion-resistant materials. It has oil, acid and alkali resistance, water resistance and wear characteristics, PTFE surface of the material does not contain lead components, food and beverage machinery, chemical industry pH meter, pump, valve, pharmaceutical machinery, printing machinery, chemical machinery marine industrial corrosion sliding parts most suitable for use Load capacity: 140N / mm2 friction coefficient:? 0.04 to 0.20 Temperature range:? -195 ~ + 280 ° C to allow the maximum PV value (dry):? 3.6N / mm2 ?. m / s maximum sliding speed:?? 2.5m / s to allow the maximum PV value (oil): 50N / mm2 .m / s?
