floating seal used in track roller, sprocket,carri

Floating Seal (Duo-cone seal) used in roller of many kinds of engineering machineries, such as hydraulic excavator, dozer, mining machinery, generator sets, oil extraction machinery, cement mixer, construction machinery and sea borne machinery. 1. The features of our floating seals as follow: 1) Material: 15CrMo cast iron, the best material in the world at present2) Hard ness is HRC: 65-723) Out Diameter: 50-865mm, Max 1500mm4) Life: over 4500 hours 5) Working face precision: less than 0.0015um 6) Flatness: 0.1um-0.2 um; 7) Pressure: 1.0-1.7MPa/cm2 (max.) 8) Temperature range: -20-90 Degree 9) Circumferential speed: 3m/ sec (max). 10) Character: high hardness,wear resisting,anti dirty ability, corrosion resistant. 2. Adapt to the brand and machine type 1) Bulldozer Japan (KOMATSU): D50, D60, D80, D85, D155, D355; American (CATERPILLAR): D58, D60, D7G, D8K, D9L, D10H; China's: SHANTUI, SHANGHAI, YELLOURIVER, YISHAN and QINGGONG; 2) Hydraulic Excavator Germany R902-R992, American CAT hydraulic excavators Japanese Komatsu hydraulic excavators; 3) Agriculture machine Japanese Kubota, Tatu oil bearing 4) Other machine Loaders,land levelers, cranes, mixers, mining machines, etc. 3. Technology Our products are made of high alloy steel. The rough cast, through hot forming, is of high strength, grind the uneven edge. The metal structure is improved through repeated heat treatment, thus the product wears well and the precision is achieved.
