Sob-1x oil-free bearing is a kind of sliding bearing which is made of steel plate, sintered spherical bronze powder in the middle, and the mixture of polytetrafluoroethylene (PTFE) and lead rolled on the surface. It has the characteristics of small friction coefficient, wear resistance, good corrosion resistance and oil-free lubrication. Using the product can reduce the cost, reduce the mechanical volume, avoid the phenomenon of shaft undercutting and reduce the mechanical noise.
The products have been widely used in the sliding parts of various machines, such as printing machines, elevators, textile machines, tobacco machines, fitness machines, hydraulic carriers, micro motors, solenoid valves, automobiles, motorcycles and agricultural and forestry machinery.
