Graphite Inlaid Oilless Gunmetal Solid Lubricant Bearings Bronze Bushings NORMAL METRIC BUSHING


JDB-1 solid lubricant embedded bearing is made of casting bronze with graphite embedded evenly in it. It has superior performance than normal bearing whose lubrication depends on oil film. Under condition of heavy duty, high temperature, slow speed, anti-corrosion or Where oil is hard to be introduced, Its performance doubles both in hardness and anti-friction It can be widely applied in continuous casting machines, mining machine, ships, air turbine, Hydraulic turbines and plastic injection molding machines.
