Datong Hydraulic

  Datong Group as a professional manufacturer of cylinder tube and cylinder piston rod ,We stock the largest range of Honed Cylinder Tubes & Unhoned Cylinder Tubes with imperial size and metric size. These steels are derived from a range of leading manufacturers from China like BaoSteel. There are key types we stock: Finished (Honed) Tubes – Honing process / SRB: Skived and Roller Burnished. Semi-finished (Unhoned) Tubes are Made from ST52 Drawn over mandrel & Cold Drawn Seamless Honed Cylinder Tube: Hot Finished E355. Advantages Of Datong Group Cylinder Tube 1, High precision tolerances; Our honed steel tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension. 2, Seamless tube with high pressure resistance; We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications. 3, High Smooth ins

  Cylinder piston rod is a very important part in hydraulic cylinder working smoothly,hard chrome plating a piece of precision equipment such as a cylinder rod is a painstaking and methodical process. The Hard Chrome Plating Process: 1. Inspection The  cylinder chrome rod  is inspected during the initial evaluation to determine the condition prior to the chroming process. An inspector will make note of any signs of corrosion, pitting, marring, damage, cracking or flaking. The presence of any of these conditions will be taken into account during the re-chroming process. 2. Grinding & Stripping Old material on the  hydraulic cylinder rod  must be removed before new chrome can be applied. This step needs to be completed carefully to preserve the steel beneath the old layer and without affecting the rod diameter. This can be done with two methods – electrolytic stripping and stone grinding. 3. Cleaning and Masking The rod then needs to be prepared to be placed in a bath of chromium so

 The  cylinder piston rod  is not just the object transmitting the force from the cylinder’s piston but also the interface between that cylinder and your machine. Before you can correctly select and then design the piston rod, you must understand the potential areas of failure. The following are the top five most common piston rod problems on  hydraulic cylinders . The rod is improperly sized for the application. This can manifest in two ways, and believe it or not, a rod can be too large. Undersized piston rods have low column strength, especially in long stroke applications. A long, thin rod will bend or break when pushing loads heavier than they’re rated. Low column strength can remedy this with a larger diameter rod or a stop tube to provide added support. Conversely, if a cylinder operates in tension, an oversized rod will actually reduce retraction force. This problem occurs at the design stage, so be sure you accurately calculate retraction force with an understanding of differ
