JDB-650 inlaid solid lubricating bearings, plain bearings belong to a series, is in high-strength brass {ZCuZn25Al6Fe3Mn4 (main chemical composition Cu Al Mn Fe Ni Zn percentages are as follows:???????? 60 ~ 66% 5.0 ~ 7.5%? 2.5 to 5.0%? 2.0 to 4.0%? 0.2 to 0.5%? 22 to 28% ?.)}, based on the mosaic graphite or MoS2 solid lubricants a high performance lubrication products. It breaks through the general bearing rely on oil film lubrication limitations. During use, the solid lubricant by friction heat of friction with the shaft, forming 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. Has been widely used in metallurgy continuous casting machine, injection molding machine, the train bracket, rolling equipment, mining machinery, ships, steam turbine and other high-temperature, high-load, low-speed heavy other occasions. Technical Specifications: Base material: CuZn25A16Fe3Mn3 Dynamic load limit: 100N / mm2 Limit PV value: Dry 1.65 Oil:? 3.5 Basic Hardness: HB210 ~ 270 friction coefficient μ: <0.16 Maximum operating temperature:?? 300 ℃ maximum sliding speed: Dry 0.5m / s oil 2m / s are available in the form of: copper sleeve, bushing, slide, slide, bearing processing: Standard | to map processing?
