Excavator Bucket Hydraulic Cylinder

Introduction to Hydraulic Cylinder of Excavator
Our company produces various brands of excavator hydraulic cylinders with complete models that can be adapted to excavators, such as KOMATSU,  CAT, HITACHI, KOBELCO, DEAWOO, DOOSAN, HyunDAI, SUMITOMO, KATO KUBOTA, ATLAS,  VOLVO, LIUGONG,
The hydraulic cylinder barrel is made of high-quality steel 27SiMn for quenching and tempering heat treatment, with a resistance strength of 980MPa. The inner hole is processed by precision boring and rolling, with a roughness of less than 0.04 microns, which improves the sealing effect of the internal oil seal of the hydraulic cylinder and the wear resistance of the support ring. The piston rod is made of high-quality steel 40Gr, subjected to quenching and tempering heat treatment, and processed through turning, surface quenching, grinding, electroplating, etc. The surface hardness reaches HRC48-55 to prevent damage from other objects. High quality steel and meticulous processing have improved the service life of hydraulic cylinder assemblies.
Customization can be made according to the drawings and standards provided by the customer.
