Single-acting cylinders apply force in how many directions?

Single-acting cylinders are designed to apply force in a single direction only. This is accomplished through the use of a piston that is pushed in one direction by hydraulic or pneumatic pressure, while the return stroke is typically controlled by a spring or by the force of gravity. The design allows for efficient operation when a unidirectional force is needed, such as pushing or lifting loads in a specific direction.

Understanding this function is important in various applications, including manufacturing and machinery, where precise control of movement is required. Because the cylinder only exerts force on one side of the piston, it's crucial for tasks where pushing is the primary action but pulling is not needed or handled differently.
