Single Acting Hydraulic Cylinders

-- Steady & Reliable Manufacturer --

For linear actuation applications that require power primarily in one direction, single acting hydraulic cylinders provide a highly efficient, cost-effective, and mechanically simplified solution. Engineered by Jiangsu Hengcai Hydraulic Mechanical Co., Ltd., these cylinders utilize hydraulic fluid pressure to extend the piston rod, while relying on gravitational pull, heavy external mechanical loads, or internal heavy-duty return springs to handle the retraction phase. This design inherently requires fewer hydraulic lines, single-direction control valves, and simplified plumbing architecture, making it an ideal choice for lift tables, dump truck beds, material handling jacks, and specialized clamping fixtures. Our single-acting cylinders are manufactured with the same high-grade steel tubing and advanced plating technologies as our complex multi-stage lines, ensuring that despite their mechanical simplicity, they deliver rugged dependability and structural longevity under demanding daily operational cycles.

Key Features

Engineering Excellence at a Glance

Feature	Technical Advantage
Simplified Fluid Circuitry	Requires only one hydraulic line, significantly lowering overall system installation costs.
Robust Gravity/Spring Return	Dependable mechanical return mechanisms reduce dependency on external fluid power.
Compact Envelope Design	Fewer internal components allow for a lightweight and highly space-efficient structure.
Reduced Maintenance Seals	Fewer pressurized sealing points translate directly to less wear and lower service overhead.

Specifications Guide

Hydraulic Cylinder Specifications Guide

Return Mechanism Options: Available in standard gravity return models or high-tensile internal spring return configurations for rapid retraction.
Surface Finish Tolerances: Piston rod surfaces are ground and polished to a microscopic finish of Ra 0.2 microns to maximize rod seal lifespan.
Vent Port Protection: Integrated breathing vents fitted with micron-rated air filtration elements to prevent dirt from entering the atmospheric chamber.
Body Wall Thickness: Heavy-gauge seamless steel body tubes designed to resist denting and external impact damage in harsh field conditions.
Mounting Hardware Compliance: Features standard base holes, rear clevis mounts, or custom threaded pins for seamless integration into existing frames.

Selection Guide

How to Select a Hydraulic Cylinder

Confirm Return Force Availability: Ensure that your machinery weight or internal spring rate is sufficient to fully retract the cylinder within required cycle times.
Evaluate Atmospheric Contamination Risks: If operating in highly dusty or wet environments, select advanced breather options to prevent internal chamber contamination.
Determine Stroke Limitations: For internal spring-return models, consider that spring length limits the maximum achievable stroke compared to gravity return options.
Match Pump Capacities: Ensure your hydraulic control valve is properly configured to vent fluid back to the reservoir during the unpowered return stroke.

FAQ

Frequently Asked Questions

Q: What is the primary difference between a ram-type single-acting cylinder and a piston-type single-acting cylinder?
A: A ram-type cylinder relies on the cross-sectional area of the rod itself to generate force and lacks internal piston seals, whereas a piston-type utilizes an internal piston head and seals to guide the rod, making it better suited for longer strokes.

Q: How do you prevent internal corrosion on the non-pressurized side of a single-acting cylinder?
A: We apply specialized internal anti-corrosion coatings and utilize high-quality filtration breathers to ensure only clean, dry air enters the cylinder during cycle movements.
