JLB-C is a high-strength copper alloy as the base material, use conditions according to a certain proportion of its work surface machined hole filled solid lubricants, high-strength copper alloys offer a high load carrying capacity and the solid lubricant can forming a low friction. The product combines the respective advantages of metal matrix and solid lubricant, breaking the general bearing rely on oil film lubrication limitations. Especially suitable for oil-free, high-temperature, high-load, low-speed, anti-fouling, corrosion, radiation, as well as under vacuum solution in water or infiltration impossible lubricating film using special working conditions. The product has been widely used in metallurgy rolling equipment, filling equipment, turbines, gas turbines, instrumentation, and mining machinery, shipbuilding, machinery, textile machinery, shipbuilding industry, space navigation and other fields.
