High Strength Copper Alloy With Solid Lubricant Plugs Casting Bronze Bearings
High Strength Copper Alloy With Solid Lubricant Plugs Casting Bronze Bearings is backed with high strength copper alloy. The surface is regularly and finely machined with sockets in which particular solid lubricant Plugs is filled. High Strength Copper Alloy With Solid Lubricant Plugs Casting Bronze Bearings is widely used on consecutive casting and rolling machines, mine-exploiting equipment, ships, steam engine, injection molders and auto molds, etc.
JDB Copper Bearings is a special formulation of high strength copper-based body surface at a certain angle and density of embedded solid lubricant specially formulated by precision machining.
Copper based and processed by turning technics. There can be made oil grooves on the inner surface and outside surface to reach a better lubricating effect. By made mid-sized holes in order and then insert the solid lubricant into the holes in the bronze bushing to apply the bushings under oil-free conditions.
