| JDB Solid Lubricant Embedded Bushing |
JDB solid lubricant embedded bushing is a new type made from strong brass and homogeneously embedded with solid lubricant in its body It breaks through the limit of general bearing whose lubrication depends on oil film. So it is suitable for high temperature, heavy duty, anti-Corrosion. or where oil is hard to be introduced It performance doubles both on hardness and wear-friction. It is now widely applied in successive casting machines, steel rollers in metallography, mineral machine, ships. steam turbine. hydraulic turbines and injection molding machines for plastics. |
