SF-1W无铅轴承

SF-1W lead-free bearing is based on steel plate, sintered spherical bronze powder in the middle, and rolled PTFE and other mixtures on the surface. It is a rolling sliding bearing. It has the characteristics of small friction coefficient, wear resistance, good corrosion resistance and oil-free lubrication. Using this product can reduce the cost, reduce the mechanical volume, avoid the phenomenon of biting the shaft and reduce the noise and so on. The steel back can be electroplated with a variety of metals and can be used in corrosive media.
