    Product details

    Material of cylinder barrelSelection of sealing partsWelding
    the product adopts 27SiMn, 45# as raw material to adjust the material so that the tensile strength (σb/Mpa): >=980, yield point(σs/Mpa): >=835;the sealing parts uses PARKER sealing gasket imported from America and BUSAK SHAMBAN supporting ring to ensure the sealing performance of the cylinder and a stable quality.through roll finish process, the product reaches perfect roughness and surface hardness, and thus improves the resistance to abrasion and gets the best cylinder rod oil film. The use of welding robots effectively prevents possible instability which is likely to happen when welding is conducted manually. It uses ultrasonic inspection to avoid weld defect.

    Our companies can customize the design, the production of all types of excavator’s hydraulic cylinder. We have sets of advanced cylinder production equipment. The cylinder liners are made of cold drawn seamless steel tubes with strong honing technique. The cylinder length can reach up to 7m with diameters from φ40 to φ500. The piston rods are made of chrome steel with special heat treatment. The diiron sing technique is applied to the surface, with makes it high in smooth finish with tough inside and hard outside. The piston rod’s diameters are from φ5 to φ180, equipped with high quality seals. The quality of our cylinders is guaranteed by the test of high-pressure test bed. We can serve you with our quality products, reasonable price, and timely delivery.
