Product Detail



High Strength Copper Alloy With Solid Lubricant Plugs Casting Bronze Slide Block

High Strength Copper Alloy With Solid Lubricant Plugs Casting Bronze Slide Block is backed with high strength copper alloy. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled.



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.



High Strength Copper Alloy With Solid Lubricant Plugs Casting BronzeSlide Blockis widely used on consecutive casting and rolling machines, mine-exploiting equipment, ships, steam engine, injection molders and auto molds, etc.



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.
