  AISI 1045  chrome plated shaft  is cold drawn, precision ground and polished shafting with a seam free surface finish of RMS 25 max. The bars are then hard chrome plated by electrolytically deposited layer of chromium metal on the surface. This hard chromed surface confers the important properties of corrosion resistance and wear resistance; it is also very smooth and therefore has a low coefficient of friction. Not least of all, it has an attractive and durable decorative appearance. Stainless Steel is an iron-based metal alloy, with added elements including chromium, nickel, silicon and carbon. These elements are mixed into the base material itself, and are present throughout the entire structure of the shafts.   The surface of the Stainless Steel is then finely polished to a mirror finish. Because the Stainless properties are evident throughout the entire bar, any damage or scratches can simply be re-polished to expose the fresh new material underneath. As a pro...

  Hydraulic cylinders are essential pieces of hydraulic engineering equipment. They are considered as common as pumps and motors combined, so if a hydraulic cylinder fails it can impact your entire operation. Reducing cylinder failure within hydraulic systems is important to avoid unnecessary  lengthy equipment down time. BENT RODS Bent rods are a common cause of rod seal failure. Bending of hydraulic cylinder rods can be caused by insufficient rod diameter or material strength, improper cylinder mounting arrangement or a combination of all three. Once a rod bends, excessive load is placed on the rod seal resulting in premature failure of the seal. we have the engineering expertise to calculate the permissible rod loading for cylinders in existing and new applications. BALLOONED BARREL TUBES Ballooning of c ylinder barrel tubes  is usually caused by insufficient wall thickness and/or material strength for the cylinder’s operating pressure. Once the tube balloons, the corr...

 The hydraulic steel tube is cylinder-like shaped tubing device that when attach to hydraulic systems, allow for the passage of fluids within and among components. The tube standard specifies dimensions for cold drawn finishing and ​seamless precision steel tubes. Cold drawn process provides the tube with close dimensional tolerances, increase material strength and enhanced machinability. Therefore, hydraulic tubes are suitable in high performance piping system application. Hydraulic steel tube is basically divided into the hydraulic system with fluid pipe and oil cylinder, also known as honing tube, and cold drawn or cold rolled precision seamless steel pipe also contains hydraulic tube. Hydraulic pipe after finishing, no oxidation bright heat treatment of raw materials (NBK), nondestructive testing, steel pipe inner hole through high pressure washing, pickling, block on both ends of the steel tube inside and outside wall with anti-rust oil antirust proce...

  CK45 Hard chrome plated bars  are chromium-plated steel products that can be supplied as piston rods in standard hydraulic and pneumatic applications. The chrome plated steel bar is normally used in conditions of high stress, friction and harsh climactic environments, so the quality of the base metal and subsequent surface treatment are of paramount importance. Wear resistance, corrosion resistance, surface smoothness, high yield strength and uniform quality are essential properties of hard chrome bar. Hard Chrome Plated Piston Rods are widely used in hydraulic and pneumatic cylinder, printing machinery, textile machinery, engineering machinery, wood working machinery, etc. Our products are highly appreciated by our clients for their features like corrosion resistance, robust construction, elevated durability, high tensile strength and the mirror-like surface. APPLICATIONS ￭ Hydraulic cylinder ￭ Pneumatic cylinder ￭ Precise machine pipes ￭ Agriculture mac...

  HYDRAULIC HONED PRECISION TUBES Hydraulic honed tubes  are seamless, hot rolled and honed. They can be used for manufacturing any hydraulic cylinder. Honing is finishing method whose goal is to ensure perfect surface grade, in our case final treatment of the inner diameter of the tube. Advantage of this classic procedure is high geometrical accuracy of the shape with minimal conicity and waviness of the surface. However, after the process, they will be a large number of spiral grooves from the grinding tool. These result in greater wear and lesser lifespan of the seals, compared to the roller burnished tubes. Final surface will have roughness Ra 0,4 μm. Hydraulic Honed Tubes are made of ST52.0 (E355) material. ST52 Hydraulic Cylinder Tubes are preferred in various sizes and thickness by our clients all across the globe. SKIVED AND ROLLER BURNISHED PRECISION TUBES These tubes are cold drawn, skived and roller burnished. They can be used for manufacturing any hydraulic cylinde...
