Strengthening Brass With Solid Lubricant Casting Bronze Bearings
Strengthening Brass + Solid Lubricant Bearings is backed with strengthening brass that has good physical performance and good capability for casting.
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. Strengthening Brass + Solid Lubricant Bearings is widely used on consecutive casting and rolling machines, mine-exploiting equipment, ships, steam engine, etc.
