High Strength Bronze Alloy With Solid Lubricant Casting Bronze Bearings
High Strength Bronze Alloy With Solid Lubricant Casting Bronze Bearings is backed with high strength copper alloy. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled. High Strength Bronze Alloy With Solid Lubricant Casting Bronze Bearings is widely used on consecutive casting and rolling machines, mine-exploiting equipment, ships, steam engine, injection molders and auto molds, etc.
Bronze 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.
