Double acting hydraulic cylinder

Double-acting cylinders transmit hydraulic power in two different directions, with both pulling and pushing force. They are formed as a piston sealed with two chambers in the cylinder.
The power transfer section of the cylinders compressive chamber is inside the cylinder tube diameter area. The force area of ​​the cylinders compressive chamber is inside the cylinder tube diameter area minus the rods cross-sectional area (outside diameter).

These types of cylinders are often fitted with one oil connection to the tension side and one oil connection to the pressure side.
