Solid Lubricant Casting Bronze Bushing Bearing For Machine Tools
Tin-Bronze With Solid Lubricant Casting Bronze Bearings
Tin-Bronze With Solid Lubricant Casting Bronze Bearings is backed with Tin-Bronze. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled.
JDB Bearings 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.
Tin-Bronze With Solid Lubricant Casting Bronze Bearings are mainly used in conditions of light load, temperature and mediate running velocity. For instance, Tin-Bronze With Solid Lubricant Casting Bronze Bearings could be used on no oil parts on the building, metallurgy and transportation machines.
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.
