Single Acting Hydraulic Cylinder Overview
Single acting hydraulic cylinder uses hydraulic pressure to extend the piston in one direction, and a spring or external force to return it. It features a simple structure, reliable performance, and easy maintenance. Widely used in lifting, pushing, clamping, and pressing applications across industrial, mobile, and agricultural equipment.

Recommended Single Acting Cylinder Types
Single acting hydraulic rams are available in different return methods, bore sizes, stroke ranges, and structural designs. Choose the right cylinder type according to your load direction, return method, installation space, working cycle, and equipment safety requirements.
Spring Return Cylinder
Best for automatic reset, compact mechanisms, presses, clamps and equipment requiring predictable return without a second oil port.
Load / Gravity Return Cylinder
Suitable for lifting, tipping and hoisting systems where the load naturally retracts the rod when pressure is released.
Single Acting Ram Cylinder
Designed for pushing and lifting applications requiring high thrust, simple structure and rugged performance in harsh environments.
Hollow Plunger Cylinder
Used for tensioning, pulling and special tooling systems where the center hole allows rods, cables or bolts to pass through.
Small Bore Cylinder
For compact machinery, agricultural implements and space-limited equipment where stroke control and leakage prevention still matter.
Heavy-Duty Cylinder
Built with stronger tube, piston rod, seals and surface treatment for heavy load cycles, shock load and outdoor operation.
What Is a Single Acting Hydraulic Cylinder?
Single acting spring return hydraulic cylinder has one hydraulic port. Hydraulic pressure extends the piston in one direction, while a built-in spring or external load returns it to the original position.
It has a simple structure, low cost, and easy maintenance, making it ideal for lifting, clamping, pushing, and pressing applications.
☑ Use it when your equipment only needs powered movement in one direction.
☑ Choose spring return when automatic reset and safer retraction are required.
☑ Avoid it when you need powered extension and powered retraction under full control.
How Does a Single ActingHydraulic Cylinder Work?
1. Hydraulic Pressure Extends
Hydraulic fluid enters the cylinder, pushing the piston and extending the rod.
2. Hold Pressure
The cylinder holds the load when pressure is maintained.
3. Spring or External Force Returns
When pressure is released, the spring or external force returns the rod to the original position.
Key Features & Benefits
- Simple One-Port Design - Easy to install, maintain, and use for lifting, pushing, and clamping.
- Reliable Return Action - Spring or external force ensures smooth return after pressure release.
- Compact Structure - Fits limited spaces and lightweight equipment.
- Stable Pressure Performance - Delivers consistent force and reliable load holding.
- Leak-Resistant Sealing - Quality seals reduce leakage and maintenance.
- Suitable for Harsh Environments - Durable materials and coatings withstand tough conditions.

Frequently Asked Questions
1.How does a single acting hydraulic cylinder return?
A single acting hydraulic cylinder returns by a built-in spring, external load, or gravity after hydraulic pressure is released. The return method depends on the cylinder structure, installation direction, and equipment working condition.
2.What is the main difference between single acting and double acting hydraulic cylinders?
A single acting hydraulic cylinder uses hydraulic pressure in one direction only, while a double acting hydraulic cylinder uses hydraulic pressure for both extension and retraction. Single acting cylinders are simpler, easier to maintain, and suitable for lifting, pushing, clamping, and gravity-return applications.
3.What sealing systems do you use?
We use PU, NBR, PTFE, and other sealing materials according to working pressure, oil type, temperature, speed, and operating environment. The right seal helps reduce leakage, improve stability, and extend cylinder service life.
4.Can you customize bore size, stroke length, pressure, and mounting style?
Yes. ZHY Hydraulic can customize bore size, stroke length, working pressure, rod diameter, mounting style, sealing system, surface treatment, and color according to your drawings, samples, or equipment requirements.
5.What information should I provide for a quotation?
You can send us the cylinder drawing, bore size, stroke length, working pressure, mounting type, rod diameter, retracted length, extended length, oil port size, quantity, and application details. If you do not have a drawing, our team can help review your sample or basic dimensions.
6.How do you test hydraulic cylinders before delivery?
Each hydraulic cylinder goes through dimensional inspection, weld checking, assembly inspection, seal leakage testing, and pressure testing before shipment. This helps confirm stable performance, safe operation, and reliable sealing.
7.What applications are single acting hydraulic cylinders suitable for?
Single acting hydraulic cylinders are commonly used in hydraulic jacks, lifting platforms, dump trucks, agricultural machinery, material handling equipment, sanitation vehicles, presses, clamps, and equipment requiring one-direction hydraulic force.
8.Can you produce single acting hydraulic cylinders for OEM projects?
Yes. We support OEM and ODM production for machinery manufacturers, equipment repair companies, and hydraulic system suppliers. Custom options include logo, color, packaging, mounting design, pressure rating, sealing system, and drawing-based manufacturing.
