There are many types of hydraulic cylinders for sale, with these being the four most common:
SINGLE-ACTING CYLINDERS
Single acting hydraulic cylinders produce power when hydraulic fluid enters a single port and flows into the cylinder and causes the cylinder to retract. Also called push cylinders, they feature a single-acting piston that moves in one direction and requires a motor or spring to reset its position.
DOUBLE-ACTING CYLINDERS
In double acting hydraulic cylinder models, fluid moves into one port and exits through a second port, forcing the cylinder to retract and extend. With two pressurized chambers, double-acting pistons do not require a spring or motor to operate.
Hydraulic equipment and machines utilize single-acting and double-acting cylinders, and each type has its advantages. Single-acting cylinders are simpler and easier to maintain than double-acting cylinders. However, with more fluid in the pressurized chamber, double-acting actuators are easier for an operator to control.
