Oil Cylinder

  公司可根据客户要求设计、制作各类挖掘机的液压油缸,选用精密冷拔无缝钢管,强力珩磨工艺;缸径规格从φ40-φ500,长度可达7米,活塞杆选用40Cr,采取先调质后再表面高频淬火,外表面镀硬铬工艺,使其内韧外硬,表面光洁度高,活塞杆直径φ5-φ180,并选用优质进口密封件,出厂的油缸均经过高压试验台检测,有可靠的质量保证。

we can design and produce hydraulic cylinders according to customers’ requirements. 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 duriron sing technique is applied to the surface, which makes it high in smooth finish with tough inside and hard outside. The piston rods’ diameters are from φ5 to φ180, equipped with quality NOK 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.
