The pressure force of the hydraulic fluid in double-acting hydraulic cylinders is used to move the piston rod in both directions. The hydraulic fluid is fed into different cavities of a hydraulic cylinder providing force in the forward and reverse directions. This type of hydraulic cylinder has a complex design and is more costly to manufacture, but due to its operating principle it makes it possible to reduce the cost of manufacturing equipment where these hydraulic cylinders are used.
Production of Double-Acting Hydraulic Cylinders
Eurobalt manufactures double-acting hydraulic cylinders with single-ended and double-ended piston rods.
In the cylinder with a single-ended piston rod, hydraulic fluid is fed into the rod cavity under pressure extending the rod. For actuating a reverse stroke, the fluid flows into the piston area and, as the piston moves, it drains out of the rod cavity through the drain port. The force of fluid pressure is different during forward and reverse strokes. This is one of the most important parameters to consider before ordering such a hydraulic cylinder. If needed, we can produce a double-acting telescopic hydraulic cylinder.
If it is necessary to use a double-acting hydraulic cylinder with the same force in both directions of movement of the rod, our company can produce a hydraulic cylinder with a double-ended piston rod. In this cylinder, two rods will be connected with one piston. This design allows us to have two rod cavities which will be filled with hydraulic fluid at the same pressure. This will ensure that the hydraulic cylinder will operate with the same force in both directions.
Eurobalt Grupp ensures production and supply of qualified hydraulic cylinders through the use of high-quality seals, steels, mandatory testing and general balancing. Therefore, in order to select the right double-acting hydraulic cylinder, it is best to leave a request on our website or contact our experienced managers who will help you choose a hydraulic cylinder of any design for your operating conditions.
