Self-lubricating Bearings

Product Details

Graphite copper sleeve, also known as self-lubricating bearing, graphite copper sleeve is in the copper sleeve as a high-strength copper alloy matrix friction surface developed with orderly, appropriately sized holes, and embedded graphite or molybdenum disulfide as a solid lubricant as a self-lubricating product to replace the traditional oil groove copper sleeve, can be used in not easy to refuel, long-term oil shortage or oil-free environment, to make up for the traditional copper sleeve need to be refueled regularly.

It has the characteristics of high bearing capacity, impact resistance, high-temperature resistance and strong self-lubrication ability, especially suitable for heavy load, low speed, reciprocating or swinging and other occasions where it is difficult to lubricate and form an oil film. Because of its high hardness and strength, and low cost, in low-speed heavy load occasions service life than twice as high as ordinary copper sleeve, graphite copper sleeve has been widely used in engineering machinery, metallurgical machinery, mining machinery, locomotive support, rolling equipment, ship machinery, mold equipment, textile machinery, gas turbine, mold and other low-speed heavy load, high-speed light load and other occasions.
