  Hydraulic cylinders can be repaired, but you should never attempt these repairs on your own. Although hydraulic cylinders have a simple design, you must be familiar with them in order to efficiently repair them. When a technician performs hydraulic cylinder repairs, they take the entire mechanism apart and reassemble to find the root cause of the issue. COMMON POINTS OF HYDRAULIC CYLINDER FAILURE There are several common points of hydraulic cylinder failure. These include the piston, cylinder rod , seals, and head. PISTON The pistons in hydraulic cylinders are one of the most common points of failure. This is especially true in light-duty applications. The pistons used in light-duty applications are often made from aluminum, which wears out much more quickly than the steel used in heavy-duty applications. When checking pistons for failure, technicians will often measure the diameter of the piston. The piston’s diameter in relation to the bore directly affects the amount of hydra...

  Honed   or Skiving and burnishing  are the two common for   cylinder barrel   production.   Datong Hydraulic   as a professional manufacturer, we only use   cold drawn seamless tube   to manufacture cylinder tubes For a hydraulic cylinder to operate effectively, the cylinder’s ID must be precisely round and have a mirror-like surface finish to ensure a tight seal between it and the mating internal piston. This is commonly achieved through skiving and subsequent  roller burnishing  inside a tubular workpiece. Skiving uses a set of carbide blades positioned around the diameter of a tool to slice away chips and create a geometrically round bore. Roller burnishing, a cold-working process, uses multiple rollers to compress the peaks of material left behind after skiving to generate an extremely smooth surface finish. Burnishing also introduces a residual stress layer into the cylinder wall, which improves cylinder fatigue life. The tub...

  DIN 2391 ST35 NBK Seamless Tubes come under AISI, DIN, EN, GB and other international standard specifications. they range from 4mm to 219mm in outer diameter with wall thicknesses ranging from 0.5mm to 20mm.  ST35 Seamless tubes are frequently used for high heat and pressure applications in oil and gas( high pressure oil pipes ) petrochemical, hydraulic cylinders & pneumatic cylinder,mechanical and Automotive engineering petroleum, and other industries. They come in various sizes and forms, including round, square, and U-shaped. Furthermore, these stainless steel tubes’ strength and corrosion resistance are well known. They are frequently produced with a seamless finish and can be used in many different sectors. ST35 is one of the best choices among the various types of steel tubes for low-cost, low-corrosion pipes. It has muscular tensile and yield strength and may be formed into round, square, or oval tubes. These stainless steel tubes’ ability to be welded without an...

  Honed Barrel SS304 is a very common  material for hydraulic cylinder manufacturers , 304 stainless steel is the most widely available of all stainless steels in the wire mesh industry, aside from the countless combinations of mesh opening sizes and diameter wire available both from stock and through manufacturing. 304 SS exhibits many benefits and is largely considered the standard of the industry. 304 SS has excellent corrosion resistance in a wide range of environments. And it is used in a wide range of applications. ADVANTAGES OF DATONG’S Honed Barrel SS304 1, High precision tolerances; Our stainless steel honed 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 stainless steel honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applic...
