Enpuda cylinders are mainly divided into two types: standard cylinders and non-standard cylinders. The standard cylinders are mainly CDL1, CDH1, CDH2 and CDT3 in the Rexroth series and other series. Main application areas: metallurgy, petroleum, mining, water conservancy, heavy industry, electric power, cement, ships, machine tools, etc...
Features:
Installation dimensions are in accordance with ISO6020/2, DIN24554 and NF/ISO 6020/2;
Flexible connection method;
Piston diameter: 25mm to 500mm; piston rod diameter from 12mm to 250mm;
The stroke length is up to 10m;
Integrated guide sleeve for quick maintenance work;

Technical data:
standard:
The main dimensions such as piston diameter and piston rod diameter conform to DIN ISO 3320.
Rated pressure: 250bar
Test pressure: 375bar
For higher working pressure, please consult our company.
The specified working pressure is suitable for impact working conditions. Under special loads, such as high working cycles, the strength of the mounting parts and the threads on the piston rod must be checked.
Installation location: any
Hydraulic oil, mineral oil according to DIN51524 (HL, HLP)
Phosphate (HFD-R) is suitable for sealing form "C"
HFA (temperature: +5 degrees to +55 degrees), water glycol HFC, please consult our company.
Temperature range: -20 degrees to +80 degrees
Viscosity range: 2.8 to 380mm2/s
Cleanliness: The maximum allowable cleanliness of hydraulic oil is based on NAS1638T grade 10. It is recommended that the lowest filtration ratio be β10 greater than or equal to 75.
Speed: 0.5m/s (depending on the size of the connecting oil port)
Acceptance: Each hydraulic cylinder is carried out in accordance with national standards, and hydraulic cylinders whose application data differs from the above data can be supplied as required.
Life: Rexroth's hydraulic cylinders correspond to the reliability recommendations for industrial applications.
Under the condition that the maximum operating speed is 0.5 m/s and the piston rod is unloaded, it is ≥ 10 000 000 double stroke during continuous operation without load, or 3000 km stroke at 70% of the maximum working pressure, the failure rate is less than 5 %.
