Aluminum-Copper With Solid Lubricant Plugs Casting Copper Silde Block
Aluminum-Copper Solid Lubricating Plugs Silde Block is backed with Aluminum-Copper alloy with good capability of mechanics, castings and anti-erosion. The surface of Aluminum-Copper Solid Lubricating Silde Block is regularly and finely machined with sockets in which particular solid lubricant plugs is filled.
Aluminum-Copper Solid Lubricating Silde Block is widely used conditions with mediate load but higher temperature and condition with mediate running velocity etc.
The surface of Aluminum-Copper Solid Lubricating Silde Block is regularly and finely machined with sockets in which particular solid lubricant plugs is filled.
JDB Copper Bearings is a special formulation of Aluminum-Copper based body surface at a certain angle and density of embedded solid lubricant specially formulated by precision machining.
