Custom Double Acting Hydraulic Cylinder
Toleng custom double acting hydraulic cylinders deliver powerful bi-directional force for both extension and retraction. With hydraulic pressure applied to both sides of the piston, these cylinders provide precise position control, fast response, and maximum efficiency — making them the most versatile and widely used cylinder type across construction, industrial, and mobile equipment.

What Is a Custom Double Acting Hydraulic Cylinder?
A double acting hydraulic cylinder is a linear actuator that uses hydraulic pressure to generate force in both extension and retraction directions. Unlike single acting cylinders that rely on gravity or springs for return, double acting cylinders have two fluid ports — one at each end — allowing pressurized fluid to drive the piston in both directions.
With a custom double acting cylinder, you get a cylinder engineered to your exact specifications — custom bore sizes, stroke lengths, mounting configurations, rod materials, seal systems, and port locations. Bore sizes typically range from 1" to 12" with strokes up to 300", making them suitable for virtually any application requiring precise bidirectional control.
Why Choose a Double Acting Cylinder?
Double acting cylinders offer significant advantages over single acting cylinders
| Feature | Double Acting | Single Acting |
|---|---|---|
| Force Direction | ✅ Both extension and retraction | Extension only |
| Control Precision | ✅ Excellent — bi-directional control | Limited — extension only |
| Return Method | ✅ Hydraulic pressure (controlled) | Gravity or spring (uncontrolled) |
| Speed Control | ✅ Both directions | Extension only |
| Efficiency | ✅ Higher — full cycle power | Lower — return is passive |
| Best For | Most applications requiring bidirectional control | Simple lifting, pressing applications |
Key Features
Why Toleng custom double acting cylinders are the preferred choice for demanding applications

Frequently Asked Questions
Quick answers about custom double acting hydraulic cylinders
What is a double acting hydraulic cylinder?
A double acting hydraulic cylinder uses hydraulic pressure to generate force in both extension and retraction directions, providing precise bidirectional control.
How does a double acting cylinder work?
Hydraulic fluid is supplied to one side of the piston for extension and to the other side for retraction — both directions are hydraulically powered.
What is the difference between single acting and double acting?
Single acting cylinders extend under pressure and retract by gravity or spring. Double acting cylinders use hydraulic pressure for both extension and retraction.
What bore sizes are available?
Standard bore sizes range from 1" to 12" (25.4mm to 305mm), with custom sizes available upon request.
What pressure can double acting cylinders handle?
Toleng double acting cylinders are rated up to 5,000 PSI (345 bar) standard, with higher pressure options available.
Can you customize mounting styles?
Yes, we offer clevis, flange, trunnion, cross-tube, foot, and custom mounting configurations.
How long does the custom manufacturing process take?
Prototypes typically 2-4 weeks. Production runs 4-6 weeks. Expedited options available for urgent requirements.
What applications use double acting cylinders?
Construction equipment, industrial machinery, agricultural equipment, mobile equipment, material handling, and machine tools.
