WHAT MATERIAL IS USED FOR THE CYLINDER BARREL?

图片
  As the main component of the hydraulic cylinder, the processing quality of the   cylinder barrel  directly affects the life and reliability of the entire product. The cylinder has high processing requirements, and its inner surface roughness is required to be Ra0.4 ~ 0.8um, and the requirements for coaxiality and wear resistance are strict. Generally, it is processed and produced by the principle of  honing  or rolling. The common materials of cylinder barrel are SAE1020, 1026, 1045,  ST52 seamless honed tubes , the steel tube is honed or rolled to meet the roughness requirement within 0.4μm. The low-pressure oil cylinder can use 1020 steel pipe, and the high-pressure oil cylinder can use CK45 steel pipe. As a professional cylinder barrel supplier, manufacturer,exporter in China,  Wuxi YUTONG  has more than 20 years production experience, we sell hydraulic honed tubing to customers and provide full range of technical support. Imperial sizes...

CYLINDER ROD HARD CHROME PLATING AND GRINDING

  Cylinder rod is a very important part for hydraulic cylinder, Wuxi YUTONG as a professional manufacturer of cylinder piston rod, we will have many steps to guarantee the quality of the rod, like  Inspection，grinding & peeling,cleaning & masking, and then hard chrome plating . Hard chrome plating, and then OD grinding is an excellent answer for repairing and/or providing wear resistance to parts such as cylinder shafts , rolls, hydraulic cylinders, rams, pistons and rods.   It is used in everything from plating jewellery with gold to applying reflective metal plating to satellites and spacecraft. In this process, objects to be plated are placed in a bath containing a solution of dissolved metal molecules (in our case this metal is a special Chromium formulation). Electrodes are attached to the object to be plated and a positive current is applied to the solution. As the current runs through the solution and out through the electrodes, it causes the dissol...

The Hardness Of Induction Hardened Bar

图片
  The process of   induction hardened bar   can enhance the mechanical properties of ferrous and alloy components in a specific part. Typically, the material of doing induction hardening includes  CK45 , 20MnV6,  4140  and 4340. First, the piston rod will be put into a copper coil, and it’s heated by alternating current. Then, the outer surface of the  cylinder piston rod  will be heated to a temperature above the transformation range. After that, the piston rod will be tempered immediately to adjust the hardness level.  The final surface hardness of the induction hardened rod will be HRC 55° ± 2°. The chrome layer hardness is 850 HV0.1. The surface hardness in the induction hardened zone immediately beneath the chrome layer is 55 HRC min. The depth of hardening is between 1.0 and 3.0 mm depending on dimension. As a professional  chrome plated bar  supplier, manufacturer,exporter in China,  Wuxi YUTONG  has more than 20 ye...
