[Application Features] self-lubricating rails, copper slide / slide / slide, self-lubricating graphite wear plate is in high strength brass substrates. Set with graphite or MoS2 solid lubricants a high performance of solid lubricant. It breaks through the general bearing rely on oil film lubrication limitations. During use, heat through friction solid shaft lubrication and friction, the formation of oil, lubrication powder coexist excellent condition, both to protect the shaft does not wear, and solid lubrication characteristics eternity. It's harder than twice as high as the copper sleeve, wear it twice. [Application] The product has been used in metallurgy continuous casting machine, the train bracket, rolling equipment, mining machinery, ships, gas turbines and other high-temperature, high-load, low-speed heavy and other occasions. The main parameters of self-lubricating guide matrix material: CuZn25A16Fe3Mn3 Dynamic load limit: 100N / mm2 basic Hardness: HB210 ~ 270 friction coefficient μ: <0.16 maximum operating temperature: 300 ℃ maximum sliding speed: Dry 0.4m / s oil 5m / s
