Strengthening Brass Cast Bronze Bearings Slide Block -40~+300℃
Strengthening Brass With Solid Lubricant Casting Bronze Slide Block
JDB Slide Block is backed with strengthening brass that has good physical performance and good capability for casting.
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.
Both vertical and horizontal direction of motion direction.
By made mid-sized holes in order and then insert the solid lubricant into the holes in the bronze bushing to apply the bushings under oil-free conditions.
Strengthening Brass + Solid Lubricant Slide Block is widely used on consecutive casting and rolling machines, mine-exploiting equipment, ships, steam engine, etc.
What’s more, the brass backing has pretty good anti-erosion ability in air, fresh water and seawater. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled.
