ZYB-1S stainless steel corrosion-resistant bearings are made of stainless steel as the matrix, sintered with corrosion-resistant alloy powder in the middle, and surface-rolled with low-friction materials mainly made of polytetrafluoroethylene. It is a very effective corrosion resistance formed by coiling. Material. It has the characteristics of oil resistance, acid resistance, alkali resistance, sea water resistance and abrasion resistance. The PTFE material on the surface does not contain lead. It is most suitable for use in food and beverage machinery, chemical pumps and valves with moderate acid-base flow, special medicine machinery, printing and dyeing machinery, chemical machinery, and marine industries.
