[Application Features] JFB burring copper-inlaid solid lubricating bearings, it is in high force brass substrate. Mosaic graphite or MoS2 solid lubricants a high performance of solid lubricant. It broke through the general bearing rely on oil film lubrication limitations. During use, heat through friction solid shaft lubrication and friction, forming oil, lubrication powder coexist excellent condition, both to protect the shaft is not worn, and the solid lubrication characteristics eternity. Its hardness twice as high than the average copper sleeve, wear resistance is also twice as high. [Application] before the product has been used in metallurgy continuous casting machine, the train bracket, rolling equipment, mining machinery, shipbuilding, gas turbines and other high-temperature, high load, low speed and heavy and so on. The main parameters of self-lubricating bearing materials: CuZn25A16Fe3Mn3 Dynamic load limit: 100N / mm2 basic hardness: HB210 ~ 270 friction coefficient μ: <0.16 maximum operating temperature: 300 ℃ Highest sliding velocity: Dry 0.4m / s oil 5m / s
