Single-Acting Hydraulic Cylinders

The workhorse of hydraulic lifting: pressure drives the ram out, and a spring or the load itself brings it back.

How Single-Acting Cylinders Work

In a single-acting cylinder, hydraulic oil is pumped into one side to push the ram out and generate force. When you release the pressure, an internal spring, or gravity and the load, returns the ram to its starting position. It's the simplest, most economical cylinder design, and it handles the vast majority of lifting, jacking and pressing work.

When to Choose Single-Acting

Reach for a single-acting cylinder any time you only need force in one direction: foundation lifting, structural jacking, pressing, bending and general construction. With fewer moving parts, they're rugged, forgiving and easy to service in the field.

Any time you only need force in one direction: foundation lifting, structural jacking, pressing, bending and general construction. Fewer moving parts makes them rugged, forgiving and simple to run.

What brings the ram back. Spring-return uses an internal spring. Load-return relies on the weight of the load pushing the ram back once pressure is released, which means it needs a load on it to retract.

No. Pulling needs hydraulic force in both directions, which is a double-acting cylinder. Trying to pull with a single-acting is the wrong tool for the direction of travel.
