■ Summary

Our company has a history of over 20 years in producing C25/D25 series high-pressure heavy-duty hydraulic cylinders. We have developed C25/D25 series hydraulic cylinders with proximity switches and C25/D25 series hydraulic cylinders with built-in sensors, providing users with a wide range of choices.
● Applicable media: mineral oil, water ethylene glycol, or other media.
● Maximum working pressure: 25Mpa Static test pressure Ps=37.5Mpa
● Maximum working pressure: 25Mpa Static test pressure Ps=37.5Mpa
● Medium viscosity range: kinematic viscosity 2.8mm2/s~380mm2/s (1cst=1mm/s)

● Maximum operating speed: 0.5m/s

● Type and specifications: The regular type has a total of 16 cylinder diameter specifications, each with 2 × 8 assembly forms, forming 256 varieties. The hydraulic cylinder is a double acting single piston type, which can be divided into differential cylinder and constant velocity cylinder, with adjustable buffer (or without), and can also be equipped with a protective cover.

● C25 and D25 series hydraulic cylinders can all be equipped with proximity switches. Its characteristics: High voltage resistant inductive proximity switches are installed at both ends of the hydraulic cylinder to control the reversing of the positions at both ends of the stroke. This structure adopts non-contact sensitive components, which are non-contact, wear free, accurate output signals, safe and reliable, high voltage resistant, easy to install and adjust, and eliminates the cumbersome mechanical reversing device. Provide great convenience for design, production, manufacturing, installation, and adjustment.

● C25 and D25 series hydraulic cylinders with a cylinder diameter of D=50-400 (except for D=40) can be equipped with built-in displacement sensors. Its feature: It can control the hydraulic cylinder to send accurate control signals at any desired position according to the working conditions. Fully utilized the mechanization and automation functions of hydraulic cylinders. With multiple output modes such as analog, digital, and bus, it is sensitive and responsive, achieving high-speed and accurate industrial automation control.

The hydraulic cylinder is a double acting single piston type, which can be divided into differential cylinder and constant velocity cylinder, with adjustable buffer (or without), and can also be equipped with a protective cover.

● The basic parameters comply with ISO and GB standards, and the installation type and dimensions comply with international steel company standards. It is consistent with the "CD250, CG250" series from REXROTH and the "DIN TAPE200/250" series from FOSSA in Italy, as well as the "SERIES 250K" series from ELRAM in the UK. It has a wide range of adaptability both domestically and internationally, making it easy for international communication.

● Widely used: This series of hydraulic cylinders is suitable for various industrial sectors, such as metallurgy, mining, lifting, transportation, shipbuilding, forging, casting, machine tools, coal, petroleum, chemical, scientific research, military, etc.

● Seals and guide components: All can be domestically produced or imported components can be used according to user requirements.

● We can design and manufacture derivative products of this series according to user requirements.
