Strengthening Copper With Solid Lubricant Plugs Casting Bronze Bearings
Strengthening Copper + Solid Lubricant Plugs Bearings is backed with strengthening brass that has good physical performance and good capability for casting.
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.
What’s more, the copper backing has pretty good anti-erosion ability in air, fresh water and seawater. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled. Strengthening Copper + Solid Lubricant Plugs Bearings is widely used on consecutive casting and rolling machines, mine-exploiting equipment, ships, steam engine, etc.
