Double Action Cylinders

A double action cylinder is a type of hydraulic cylinder in which force is created on both the push and pull of the piston, thereby creating force in both directions. The cylinder contains inlets and seals on both sides. Due to the presence of the piston shaft on one side, the force created by a double action cylinder is unbalanced, generating more in the push direction when the full face of the piston is available.
