High Strength Copper Alloy With Solid Lubricant Casting Bronze Thrust Washer
OILES 500# Thrust Washer is backed with high strength Copper alloy. The surface is regularly and finely machined with sockets in which particular solid lubricant plugs is filled.
By made mid-sized holes in order and then insert the solid lubricant plugs into the holes in the bronze bushing to apply the bushings under oil-free conditions.
JDB Copper Thrust Washer 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.
OILES 500# 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.
OILES 500# Thrust Washer is widely used on consecutive casting and rolling machines, mine-exploiting equipment, ships, steam engine, injection molders and auto molds, etc.
