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 used on no oil parts on the
building, metallurgy and transportation machines.
JDB Copper Bearings is a special formulation of Tin-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.
