Tin - Copper Cast Bronze Bearings Slide Block Anti Abrasion For Transportation Machines

Tin-Copper With Solid Lubricant Plugs Casting Bronze Slide Block

JDB Copper Slide Block is backed with Tin-Copper. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled. OILES 500# Copper Slide Block is widely used on the anti-abrasion and anti-erosion parts, which work in conditions with heavier load and mediate running velocity.

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.

By made mid-sized holes in order and then insert the solid lubricant Plugs into the holes in the Copper bushing to apply the bushings under oil-free conditions.

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.
