  ST52.4 Hydraulic steel tubes   are tubes made in accordance to DIN 2391 / DIN 2445. ST52.4 is a high grade steel material, it can withstand higher working pressure with same tube OD size compare to ST37.4 material.  The delivery condition for grade ST52.4 tubes are in NBK finishing, which is normalized, phospated, and oiled inside and outside. Hydraulic tubes ST52.4 are measured by Outer Diameter (OD) and in varies tube thickness (THK). Difference of OD and tube thickness lead to different working pressure. ST52.4 Precision Hydraulic tube  is used in a variety of industries, including oil and gas, waterjet cutting, food processing, petrochemical/chemical, and many others for fluid handling.   Oil and gas:  The oil and gas industry has many uses for high pressure stainless steel tubing. In the field, high-pressure tubing is used for down-hole control systems, hydraulic and pneumatic piping, chemical injection modules, vacuum systems, and much more. Chemical/petrochemical:   High press

  S45C Chrome plated rod   usually used as hydraulic piston rod. It goes through the machining process of cold drawn, peeling, centerless grinding, polishing, and hard chrome plating, in order to enhance the surface hardness for friction and corrosion resistance; the material will also be easier for further machining, and its precision can achieve international standard. S45C Chrome plated bar with enhanced surface hardness and increased resistance to corrosion provided by the chrome plating, are the ideal solution for various applications in marine  hydraulic cylinders , mining industry equipment, road transport, chemical plants, civil engineering, farming machinery, off-shore industry, hydraulic and oleo dynamic, aeronautical, aerospace and nuclear. Diameter Tolerance Of S45C Chrome Plated Rod As a professional S45C chrome plated rod supplier, manufacturer,exporter in China,  Wuxi YUTONG  has more than 20 years production experience, will do production with ISO f7/f8 tolerance for ch

  AISI 4140 SCM440 steel round bars   is made of medium carbon chromium molybdenum alloy steel, which is an alloy steel containing chromium and molybdenum. It has the advantages of stable composition, low harmful elements, high steel purity, small decarburization layer and few surface defects. It is easy to be spheroidized and has low cold cracking rate. SCM440 steel round bars have better strength and good comprehensive mechanical properties after heat treatment, and is easier to process under heat treatment. It has excellent quenchability, can be deeply quenched and the temper brittleness tendency is less, widely used in the production of high strength steel fasteners such as engine, mold, motor, gear, transmission parts,  cylinder piston shaft , arm, cold forging parts, screw, etc.. DESCRIPTIONS OF AISI 4140 SCM440 STEEL ROUND BARS  Standards: JIS G4051, JIS G4053 Size: φ15 - 300mm Forms: Round bar Delivery condition: Cold drawing, hot rolling, forging THE EQUIVALENT STANDARDS OF SC

ST 52-3  honed cylinder tube  is the seamless cold drawn tube made of material steel grade st52.3 for hydraulic cylinder applications, it is usually used as  hydraulic cylinder barrel . St52 steel (St52-3) is an unalloyed structural steel grade complies with DIN 17100: 1980. ST 52-3 is low carbon steel grade, excellent weldable, the most widely used steel grade used for  cylinder tubes . Normally supplied stressed relieved and annealed to either Din 2391-C for seamless tubes or Din 2393-C for welded tubes. ST 52.3 Honed cylinder tubes are highly durable and resistant to wear and tear. They are commonly used in applications where heavy loads and high pressure are present, such as in construction equipment, agricultural machinery, and mining equipment.

  A  Custom Hydraulic cylinder  is made up of a clevis, end cap, port, piston and  piston rod , a seal gland and finally a seal. This hydraulic cylinder works by pressuring a fluid sealed within the cylinder, to force the piston to extend and retract with great speed and force.  Assembling a hydraulic cylinder is a relatively straightforward process, with each part attaching to the other in a specific manner. The assembly can only begin after each part is inspected for its quality and cleanliness.  The basic steps for hydraulic cylinder assembly are: First, the seals (for the piston, cylinder head, etc.) are placed in their respective positions along with the bearing and snap ring. The cylinder head and the piston are then attached to the  cylinder rod . The seals around the cylinder head and piston are oiled. Once the piston rod is assembled, it is then ready for  cylinder barrel  installation The tube is horizontally fitted to an installation bench, in which a bearing is installed an
