TCB500 Solid Lubricating Bearing with Copper Base

: TCB500 Solid Lubricating Bearing is produced by strengthening brass that has good physical performance and good capability for casting. What's more, the brass material has pretty good anti-erosion ability in air, fresh water and sea water. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled. Its material is CuZn25Al5Mn4Fe3. The material of copper alloy could be changed as per customer’s requirements. These products are widely used on consecutive casting and rolling machines, mine-exploiting equipments, ships, steam engine, etc.
