The copper sleeve has a wide range of functions. Copper is used for plain bearings. Bearings are more economical than normal and can withstand larger loads. Copper sleeves, also known as copper bearings, require lubrication bearings. It is the lubrication of mechanical parts produced by various copper alloys. With a variety of large, heavy machinery, is an important part of the machine. Can be divided into: self-lubricating copper sleeve, need lubricating oil; graphite copper sleeve, no oil lubrication. There are many copper sleeve materials, ordinary tin bronze, aluminum bronze, brass, phosphor bronze. The casting method can be divided into metal casting model, precision casting, centrifugal casting, sand casting and large copper sleeve centrifugal casting.

Both centrifugal casting and precision casting are special castings. Centrifugal casting is the use of centrifugal force to bring the metal liquid to the edge of the mold, the final shape. The centrifugal casting model is a mold, similar to a metal casting, and the mold is reused. Precision casting is mainly used to produce wax molds. In the wax mold, refractory materials coated with different fineness, melted wax molds, and shells are then fired at a high temperature to form. Sand casting quartz sand and clay, resin, water glass and other coupling materials, the main material is quartz sand casting. The mold is used multiple times and the mold is used once. Centrifugal casting can only produce cylindrical or disc shaped castings. Precision casting can only produce small castings. Sand casting can make larger and more complex castings in batches. Can be a single, you can also mass production, more adaptable.

The application of various industries, steel mills, mines, steel roller presses and equipment copper wear-resistant copper sleeves. High demand for power plants, gas turbines, power systems, power generation equipment, and copper kits. These devices and copper are more time and enjoy the cumbersome, assembly and disassembly troubles, inconvenience compensation, so they require copper to be very stable and wear resistant. Manufacturers usually use more imports, imported copper, copper Sweden SKF, Germany FAG copper, copper sets Japan used copper and other brands. Printing, packaging machinery, food machinery, special copper and copper ball shells.
