JD HYDRAULIC MACHINERY AND PARTS LTD

We are offering sumitomo s430f2 excavator hydraulic arm/boom/bucket cylinder. made according to customers requirements:hydraulic cylinder is one of our main products, mainly used in excavators, rotary drilling rig, tunneller and such engineering machines. Through long-time heat treatment production lineprocessing introduced from japan, it is of high strength, of high accuracy and durable, please callour company for details. our hydraulic cylinders are used for excavators and other construction machinery. They are ofhigh working pressure, reliable performance, long life, easy installation, easy maintenance and soon. The seals are imported named nok. The piston rod are made of high-quality alloy steel, afterheat treatment, especially surface quenching, its hardness can reach hrc55, which can effectivelyprevent piston rod surface from bumps and strains. After the chrome-plating surface of piston rodbeing polished, the roughness of the surface is reduced and the service life of the seals is greatlyextended. the cylinder is made of alloy steel or medium carbon steel. After milling, pressing and suchadvanced processing technology, the roughness of the cylinders inside surface is reduced, thefriction gets smaller, and the service life of the seals is extended. The two ends of hydrauliccylinder are equipped with buffer devices with good performance, which effectively relieves theinertial force generated by the end of travel, reduces the high speed and peak pressure to the least, lowers the noise and impact load, and makes excavator work steadily and coherently. our cylinder is used for hitachi, komatsu, kobelco, sumitomo, daewoo, hyundai, carter, volvo, doosan, kato, etc. sumitomo excavator cylinder types sh60 armboombucket cylinder sh100 armboombucket cylinder sh120 armboombucket cylinder sh120-3 armboombucket cylindersh200a1 armboombucket cylinder sh200a2 armboombucket cylinder sh200a3 armboombucket cylinder sh200ct armboombucket cylindersh200-3g armboombucket cylinder sh210-5 armboombucket cylinder ls260 armboombucket cylinder sh300 armboombucket cylindersh300a2 armboombucket cylinder sh330a3 armboombucket cylinder sh450 armboombucket cylinder ls280ej armboombucket cylinders430f2 armboombucket cylinder ls280fj armboombucket cylinder ls280fj-2 armboombucket cylinder
