SF-2S

SF-2S oil-free lubricated bearing, is an improved product of SF-2, using steel back as the matrix, sintered spherical tin bronze powder in the middle, and a polymer material with acetal resin and containing lipophilic fibers and special lubricants on the surface. The same foreign products are DS bearings, which are suitable for dry friction and less oil lubrication under normal temperature conditions, and have the advantages of low friction coefficient, good wear resistance and oil-free lubrication. At present, the products have been used in swing movement, easy to wear, easy to corrode occasions, such as rolling machines, bulldozers, printing and dyeing machines, coal machines and cranes, driving aerial working machines and other occasions.
