HYDRAULIC POWER ONE WAY · LOAD OR SPRING RETURN
Straightforward one-direction hydraulic actuation for lifting, tipping, jacking and other return-assisted functions.
A single-acting cylinder uses hydraulic pressure for one working direction. Retraction is provided by gravity, the machine load, a spring or another external force. The simpler fluid path can be a practical choice when powered return is unnecessary and the return condition is reliable.
APPLICATION FIT
Why This Cylinder Type Is Selected
Selection should be based on machine function, load path, available space and service conditions—not only on nominal dimensions.
Simple Hydraulic Circuit
One pressure connection can reduce hose routing and circuit complexity for suitable machine functions.
Efficient Lifting or Pushing
Pressure is applied where work is required, while gravity, spring force or load handles the return.
Flexible Mobile Applications
Commonly considered for tipping, lifting and agricultural functions with predictable return loads.
TECHNICAL INPUTS
Confirm How the Cylinder Will Return
The return method is the key selection question. The available gravity load or spring force must overcome seal friction, back pressure and mechanical resistance.
- Required working force and direction of hydraulic power
- Return method: gravity, external load, spring or mechanical linkage
- Bore, rod diameter, stroke and closed length
- Working pressure, available flow and acceptable return time
- Mounting orientation, pin centers and port position
- Need for a vent, protective boot or corrosion-resistant finish

FREQUENTLY ASKED QUESTIONS
Single-Acting Hydraulic Cylinders FAQ
These answers provide a starting point. Final cylinder selection should be checked against the actual machine and hydraulic circuit.
How does a single-acting cylinder retract?
It retracts through gravity, an external machine load, spring force or another mechanical action rather than hydraulic pressure on the opposite side of the piston.
Can a single-acting cylinder work horizontally?
Only when a reliable external return force is available throughout the stroke. Orientation, friction and load direction must be confirmed.
When is a double-acting cylinder a better choice?
Use double-acting operation when both directions require positive force, controlled speed or reliable movement independent of gravity and load.
