WZB- 2 s bearing lubrication system, is the modified products WZB- 2s, for the steel back of substrate, sintering spherical tin bronze powder, surface rolling acetal resin and fiber containing hydrophilic polymer materials and special lubricants. The same products abroad are DS bearing, suitable for the dry friction and less lubrication of work under normal temperature, which has the advantages of low friction coefficient, good wear resistance and oil-free lubrication. At present, the products have been used in swing, easy wear and corrosion, such as winding machine, bulldozer, printing and dyeing machine, coal mining machine, crane and crane, etc.
