What Is a Custom Single Acting Hydraulic Cylinder?
A single acting hydraulic cylinder is a linear actuator that uses hydraulic pressure to extend the piston in one direction only. Retraction is achieved by gravity, external load, or an internal spring — eliminating the need for a second hydraulic port and simplifying the hydraulic circuit.
With a custom single acting cylinder, you get a cylinder engineered to your exact specifications — custom bore sizes, stroke lengths, mounting configurations, spring return options, and port locations. Bore sizes typically range from 1" to 8" with strokes up to 120", making them ideal for lifting, pressing, holding, and agricultural applications.
Why Choose a Single Acting Cylinder?

| Return Method | Gravity or spring (passive) | Hydraulic (active control) |
| Control Precision | Limited — extension only | Excellent — bi-directional |
| Best For | Lifting, pressing, holding, agricultural | Precision control, bi-directional force |
Key Features
Why Toleng custom single acting cylinders are the preferred choice for simple, reliable applications
Single Direction Force
Hydraulic pressure drives extension in one direction — ideal for lifting, pressing, and holding applications where only push force is required.
Cost-Effective Design
Simpler construction with one port and fewer components reduces initial cost and ongoing maintenance expenses.
Spring or Gravity Return
Retraction by internal spring or external gravity eliminates the need for a second hydraulic line — simplifying installation and operation.
Maximum Reliability
Fewer seals, fewer ports, and simpler construction mean fewer failure points and higher reliability in demanding applications.
Durable Construction
Hard chrome plated rods, precision-honed steel tubes, and robust end caps ensure long service life in demanding environments.
Customizable Options
Custom bore sizes, stroke lengths, spring rates, mounting configurations, and port locations — engineered to your application.

Frequently Asked Questions
Quick answers about custom single acting hydraulic cylinders
What is a single acting hydraulic cylinder?
A single acting hydraulic cylinder uses hydraulic pressure to extend the piston in one direction only, with retraction by gravity, external load, or internal spring.
How does a single acting cylinder work?
Hydraulic fluid enters through a single port, pushing the piston to extend. When pressure is released, the piston retracts by gravity, spring force, or external load.
What is the difference between spring return and gravity return?
Spring return uses an internal spring for retraction. Gravity return relies on the weight of the load to push the piston back, typically used in vertical installations.
What bore sizes are available?
Standard bore sizes range from 1" to 8" (25.4mm to 203mm), with custom sizes available upon request.
What pressure can single acting cylinders handle?
Toleng single acting cylinders are rated up to 3,000 PSI (207 bar) standard, with higher pressure options available.
Can you customize spring force?
Yes, we offer custom spring rates based on your application requirements — including the specific load and return speed needed.
What applications use single acting cylinders?
Hydraulic jacks, lifting platforms, agricultural implements, press machines, clamping systems, stabilizers, and outriggers.
What is the MOQ for custom single acting cylinders?
We offer flexible MOQs — from single prototypes for testing to high-volume production runs.
How long does the custom manufacturing process take?
Prototypes typically 2-4 weeks. Production runs 4-6 weeks. Expedited options available for urgent requirements.
Do you provide drawings before production?
Yes, we provide 2D drawings and 3D models (STEP, IGES, DWG) for your review and approval before manufacturing begins.
What certifications do you have?
