Graphite Bronze Bushing

WGB-1 oil-free lubricated bearing is a sliding bearing made of steel plate as the base, sintered spherical bronze powder in the middle, and rolled with a mixture of polytetrafluoroethylene (PTFE) and lead on the surface. It has the characteristics of small friction coefficient, good wear resistance, corrosion resistance, and oil-free lubrication. The use of this product can reduce costs, reduce mechanical volume, avoid shaft biting, and reduce mechanical noise. The product has been widely used in the sliding parts of various machines, such as printing machines, elevators, textile machines, tobacco machines, fitness equipment, hydraulic transport vehicles, micromotors, solenoid valves, automobiles, motorcycles, and agricultural and forestry machinery.
