 A  hydraulic cylinder  works on the principle of pressure difference. The hydraulic cylinders can be broadly categorised into: Single acting cylinders –  Where the pressure can be applied only in one direction and the return of the piston is either by gravity or other means such as pulling back (A bicycle air pressure filling pump). Double acting cylinders –  in these cylinders the pressure can be applied from both the sides. The other side acts as the return side (low pressure) in the forward stroke and acts as the main side (high pressure) in the return stroke. This cylinder has openings on both sides to allow for hydraulic oil to enter and exit (return to tank) from both sides alternately as per the stroke (forward or return). The hydraulic basically acts on the simple principle of Force and pressure. Force (F) = Pressure (P)*Area (A) The force exerted on the piston of the cylinder is equal to the pressure of the hydraulic oil multiplied by the area of the p...

  E355 High pressure steel tube  is designed to convey liquid fluids to among hydraulics components, fittings, valves, flanges, and other tools. It is made of material E355 (ST 52.4) or E235 (ST 37.4). These two grades have different chemical composition. This helps to control the working pressure.  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 hydraulic steel tube with close dimensional tolerances, increase material strength and enhanced machinability. Therefore, hydraulic steel tubes are suitable in high performance piping system application.  There are two type of material grade for  high pressure cold drawn tube , ST52.4 and ST37.4.   ST52.4 is high tensile strength tube me...

  Precision Skiving Tubes   are made from heat treatment of cold drawn, and then skived and roller burnished. They usually can be used for manufacturing   custom hydraulic cylinder   especially for big bore size.Skiving and roller burnishing is finishing method that does not remove the material in the form of chips, but rather transforms the surface layer. Precision skiving tubes from DATONG HYDRAULIC are made of ST52.3 BK+S (E355SR) material – with standard of DIN2391, low-carbon steel grade with guaranteed weldability.  The manufacturing Process Of Precision Skived roller burnished tubes Seamless hot rolled hollows are obtained with controlled concentricity on an  rolling line and then drawn to precision tubes with significant cross-section reduction improving the geometry and strengthens of the tubes. The cold deformed tubes are then Inside skived and roller burnished (SRB) using state of the art equipment and tools supplied by well-known producers with ...

 In the world of hydraulic systems, every component plays a critical role in ensuring efficiency, reliability, and longevity. Among these components, the CK45 chrome piston rod stands out as a linchpin for seamless operation.  As a key element in hydraulic cylinders, CK45 chrome piston rods are engineered to withstand extreme conditions while delivering unmatched performance. Let’s dive into why chrome-plated piston rods are indispensable and how our expertise sets us apart in this competitive industry. Core Strengths of CK45 Chrome Piston Rods Superior Corrosion Resistance Chrome plated rods are coated with a thick, hard chromium layer, providing exceptional resistance to rust, chemicals, and abrasive environments. This makes them ideal for industries like marine, construction, and agriculture, where exposure to moisture and harsh elements is unavoidable. Enhanced Wear Resistance The ultra-smooth surface of chrome-plated rods minimizes friction between the piston and custom...

  Telescopic hydraulic cylinders are critical components in heavy-duty applications such as construction machinery, material handling, and agricultural equipment. Their durability directly impacts operational efficiency and maintenance costs. While multiple factors influence their lifespan, understanding these challenges allows companies to innovate and deliver superior products. Below are key factors affecting service life, with insights into how DATOG HYDRAULIC addresses them to ensure longevity and reliability. 1. Material Quality and Manufacturing Precision The choice of materials and manufacturing accuracy are foundational to a cylinder’s performance. Low-grade steels or alloys may deform under high loads, while poor machining tolerances can lead to uneven wear or internal leakage. DATONG use high-strength, corrosion-resistant materials such as CK45 chromed piston rods and E355 ST52 cylinder tubes .  Our CNC machining and automated welding processes ensure micron-level...
