A hydraulic cylinder or jack is a type of hydraulic actuator that converts pressure into force. Hydraulic cylinders are found in a variety of hydraulic machines to apply linear force. The maximum cylinder force depends on the effective level and allowable working pressure. Important parameters of hydraulic cylinders are speed, force and course. The speed depends on the cross section and the oil fed per unit time. Depending on the design, the cylinder can generate tensile or compressive force. The most commonly used hydraulic cylinders include one-way and two-way.

• One-way cylinder: This cylinder exerts force in one direction only.
• Two-way cylinder: Two-way cylinder can transmit power in both directions.
• Manufacture of hydraulic jacks with a piston diameter of at least 25 mm. Up to a maximum of 800 mm.
• Tonnage (force) of hydraulic cylinders, depending on the design and selection of dimensions and working pressure of the cylinder can be from 100 kg to a maximum of 1000 tons.
• Normal working pressure of standard hydraulic cylinders is up to 250 bar. If needed, the company is able to manufacture hydraulic cylinders with a working pressure of up to 400 bar (for special applications up to 800 bar).
• The speed of conventional cylinders is from 0.5 to 1.5 meters per second, which can be increased up to 15 meters per second for special applications by taking precautions.
• The course of ordinary cylinders is up to 6000 mm, which the company is able to design and manufacture normal (non-telescopic) hydraulic cylinders with a course length of 14000 mm in special cases.
