Solid lubricant bearing bushing

Solid Lubricant Embedded Bushing

I
t is a new type made from strong brass and homogeneously embedded with solid lubricant in its body. It breaks through the limit of general bearing whose lubrication depends on oil film.

It is suitable for high temperature, heavy duty, anti-corrosion, or where oil is hard to be introduced. It performance doubles both on hardness and wear-friction.

It is now widely applied in successive casting machines, steel rollers in metallography, mineral machine, ships, lurbo generalors, hydraulic turbines gemel in furnace gate, convey way of the baking furnace, light industry, tooling machine industry and injection molding machines for plastics.
