Single Acting Cylinder Tubes are the one of the most important part in telescopic hydraulic cylinder working system.Single-acting telescopic cylinders use hydraulic power to extend the cylinder and gravity or mechanical force to retract the cylinder into its original position. This design is low-maintenance and compatible with most machinery. Double-acting telescopic hydraulic cylinders utilize unidirectional hydraulic power to extend and retract the cylinder. This telescopic cylinder design is best for heavy-duty applications.  these telescopic cylinders  have super processing requirements, and its inner surface roughness is required to be max Ra0.4 microns, and the requirements for coaxiality and wear resistance are strict. Generally, it is processed and produced by the principle of honing or rolling. As a experienced manufacturer of different kinds of telescopic cylinders, Wuxi YUTONG is very clear about  that the common materials of single acting cylinder tubes are ST52/ST52.3 ,

  E355 Honed Tube is well known as ST52 E355 cylinder barrel in hydraulic industries. Honed pipes/ Skived & Roller Burnished Tubes are the most important material of manufacturing hydraulic cylinders. As one of the leading hydraulic cylinder honed tube suppliers and manufacturers, Wuxi YUTONG  has been supplying and exporting  honed tube and honed cylinder barrel for almost 20 years. We produce honed steel tubes and skived roller burnished tubes used for hydraulic cylinder or pneumatic cylinder with high quality & good prices.Imperial sizes & metric sizes available.

  As we all know ,   high pressure cylinders   are very widely used for many industrial and mobile applications, including on and offshore oil industry, injection molding machines, steel industry, testing equipment and more. Cylinders are available in different types such as telescopic cylinders, tie-rod cylinders, large bore cylinders, long stroke cylinders, etc Wuxi YUTONG as a professional manufacturer of OEM designed hydraulic cylinders ,We have very rich and mature experience and technology before designing a high-pressure cylinder, we first consider the following aspects. 1. Minimize the overall size of the high-pressure oil cylinder to make the structure compact. 2. Ensure the traction force required for the reciprocating speed and stroke of the high-pressure oil cylinder. 3. The  cylinder piston rod  is not in a stretched state to avoid bending deformation. 4. Ensure that each part has sufficient strength, stiffness and durability. 5. Try to avoid the high-pressure cylinder fro

  Nickel chrome plated  is the most common electroplating technique, which uses nickel and chromium deposits to form a multilayer finish on the substrate. The motorcycle and automotive industries use this process to achieve a shiny and glossy appearance on their parts. It forms a hard outer layer that improves the corrosion and wear resistance of the substrate. In addition to metal plating, it is also used in plastic materials for decorative purposes. Nickel chrome plating technology is the solution to extreme environments with intense corrosion: offshore, marine conditions, wind, solar and aerospace sectors, agriculture,hydraulic parts like  cylinder piston rod , mining industry, oil and gas industry. Steel grades as 1045 or 38MnVS6, having a low carbon content and good weldability, are the most suitable bases for nickel-chrome plated products.

  Quenching  tempering bar mostly work under relatively large dynamic loads. They are subjected to tension, compression, bending, torsion or shear. Some surfaces also have friction, requiring a certain degree of wear resistance and so on. In short, parts work under various complex stresses. These parts are mainly structural parts of various machines and mechanisms, such as cylinder shafts , connecting rods, bolts, gears, etc. They are widely used in machine tools, automobiles, tractors and other manufacturing industries. Especially for large parts in heavy machine manufacturing, quenching and high temperature tempering is more used. Because of the different stress conditions, the properties of conditioned parts in mechanical products are not exactly the same. Generally speaking, all kinds of quenched and tempered chrome bar should have excellent comprehensive mechanical properties, that is, proper combination of high strength and high toughness, in order to ensure the long-term smoot

  Skiving tube and honing tube are both two common solutions for hydraulic cylinder barrel production. Skiving and roller burnishing is a two-in-one bore sizing and finishing process that delivers high levels of precision at lightning-fast speeds. Skiving and roller burnishing process is up to 70% faster than traditional honing process , making it an ideal solution for finishing hydraulic cylinder tubes in mass-production environments. Skiving and roller burnishing tools are used for the functional production of internal diameters of cylinder tubes . These combine machining (skiving) and roughness reduction (roller burnishing) in a single tool, allowing both processes to be carried out simultaneously. Skiving tube produces the dimensional and shape accuracy required for hydraulic cylinders, for example. Roller burnishing influences the roughness of the surface directly after machining. The usual target values here are R a 0.1µm - 0.3µm. Wuxi YUTONG as a professional manufacturer of
