Main technical parameters

■Product introduction:

1．Pressure: There are two types of this standard of hydraulic cylinders. The E-class hydraulic cylinder is suitable for hydraulic cylinders with the pressure range of 6.3MPa ~ 16MPa (referred to as E-class cylinder). C Class is suitable for hydraulic cylinders with a pressure range of >16MPa to 25MPa (referred to as C-class cylinder).
2．Sealing: E-class cylinder adopts Yx-type polyurethane sealing ring with simple structure and good wear resistance and Yx-type rubber sealing ring with wide application range. C-class cylinder adopts high-pressure-resistant and sealing-reliable V-shaped combined seal ring.
3．Dustproof: The hydraulic cylinder adopts polyurethane or nitrile rubber frameless dustproof ring.
4．Applicable medium: hydraulic oil, mechanical oil, emulsion. It is not suitable for phosphate esters.
5．Applicable temperature: -40t～+120℃.
6．Structure: The cylinders of this standard are equipped with 17 cylinder diameters (40, 50, 63, 80, 90, 100, 110, 125, 140, 150, 160, 180, 200, 220, 250, 280, 320) and two speed ratios (1.46, 2), which enable the cylinders of this standard to be of 34 different specifications. Each cylinder of the same specifications is also divided into two structures with gap buffer and without buffer. Therefore, there are 68 varieties for the above 34 specifications, which is easy for users to choose.
The cylinder head and cylinder end are equipped with one-way air-relief valves, which can be used not only for quick start of the hydraulic cylinder with gap buffer, but also for deflation.

The dustproof seal of the rod part adopts a replaceable structure, which is convenient for on-site maintenance.
The piston rod is plated with protective hard chrome, which has the advantages of dustproof, anti-corrosion, anti-rust and wear resistance.
The oil port of the hydraulic cylinder with cylinder diameter ≤220mm adopts metric fine thread.
The oil port of the hydraulic cylinder with a cylinder diameter ≥250mm adopts a closed flange.
7．Installation and connection: in line with installation and connection dimensions of series hydraulic cylinders in International Standards IS06020/1-/1981, there are 13 different installation types for cylinders with different diameters, which are basic types, front and rear long square flanges, front and rear square flanges, front and rear round flanges, front, middle and rear pin shafts, single head earrings, and axial and radial tripods. (See the model description and Table 5-17 for details). Except for the axial tripod type, the installation and connection dimensions shall comply with IOS6020/1-1981. The thread at the rod end also complies with GB2350-80.
