Tin-Copper With Solid Lubricant Plugs Casting Bronze Bearings

Tin-Copper With Solid Lubricant Plugs Casting Bronze Bearings is backed with Tin-Copper. The surface is regularly and finely machined with sockets in which particular solid lubricant Plugs is filled.



JDB Bearings 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.



Tin-Copper With Solid Lubricant Plugs Casting Bronze Bearings are mainly used in conditions of light load, temperature and mediate running velocity. For instance, Tin-Copper With Solid Lubricant Plugs Casting Bronze Bearings could be usedon no oil parts on the building, metallurgy and transportation machines.



JDB Copper Bearings is a special formulation ofTin-Copper based body surface at a certain angle and density of embedded solid lubricant specially formulated by precision machining.



JDB Bearings is widely used on the anti-abrasion and anti-erosion parts, which work in conditions with heavier load and mediate running velocity.



For instance, on light industrial machines, machine tools, moving belt in the drying machine, door of the fireplace, on no oil parts on the building, metallurgy and transportation machines, etc.
