Pull Gas Spring
Integrated damping enables gentle retraction, avoiding impact from rapid rebound of components.
Precision sealing reduces pressure attenuation, maintaining steady pulling force after repeated stretching cycles.
Unlike common push gas springs, the internal structure is designed for tension working conditions with excellent anti-fatigue performance.
Various fittings available for standard equipment and customized pull-type mechanical assemblies.
Custom pulling force and stroke for machinery, furniture, medical equipment and push-pull structures.Minimum Order Quantity (MOQ): 50PCS
Pull Gas Spring for Industrial & Commercial Use — Precision Tension Control Solution
Founded in 2002, Xingtai Juxiang specializes in pull-type gas spring production. The Pull Gas Spring differs from conventional compression gas springs, generating stable traction force via internal nitrogen pressure. It fits inward flip covers, push-pull structures and tension control assemblies for machinery, furniture, medical and automotive industries. The product features 50N–500N force range, 30–500mm stroke and -40℃ to +80℃ working temperature, with 50 PCS MOQ and customizable OEM/ODM support.
What Is a Pull Gas Spring and How Does It Work?
A pull gas spring operates opposite to standard compression gas springs, retracting the piston rod inward through sealed nitrogen pressure. It suits equipment with limited external space or scenarios requiring continuous closing and tensioning force, such as overhead doors and machine safety guards. Built-in internal damping buffers the retraction process, achieving steady closing movement without sudden snapping or rebound impact.
Key Product Features & Technical Advantages
The internal damping structure buffers the final retraction stroke to avoid component collision damage, adapting to precision machinery and medical equipment usage scenarios. Precision sealing structures reduce internal pressure loss, maintaining stable traction force after long-term repeated stretching. Optimized internal cylinder and piston structures withstand high-frequency cyclic operation and avoid fatigue failure. Multiple end fitting options including ball joint, eye and clevis simplify installation and match various mechanical assemblies.

Applications Across Industries
Pull gas springs cover multiple industrial and commercial scenarios. They provide continuous tension for mechanical safety guards to prevent accidental opening during equipment vibration. Steady and silent retraction fits medical and rehabilitation devices to avoid operation risks. For inward-opening cabinet doors and kiosk lids, they stabilize closing action and reduce component wear. The compact pull-type structure also adapts to narrow spaces of aerospace, marine and high-end vehicle equipment for stable extreme-environment operation.
Quality Control Process
All products undergo full pre-delivery testing. Dynamic force testing controls traction force tolerance within ±5%~±7%. Endurance cycle testing with 30,000–100,000 strokes verifies structural stability. Salt spray testing follows ASTM B117 standards to adapt to harsh environments. High-sensitivity leakage detection eliminates internal nitrogen micro-leaks to ensure long-term stable operation.
Customization & Supply Capabilities
We support customized force, stroke, rod/tube diameter and end fittings to meet diverse equipment demands. OEM and ODM services are available for commercial and vehicle equipment. With complete production control, we deliver stable shipments to Europe, Southeast Asia, the Middle East and other global regions.
FAQ
Q1: How is it different from standard gas springs?
A: Standard springs push rods outward; it use nitrogen pressure to retract rods inward, suited for tension and closing force scenarios.
Q2: Can traction force be adjusted after installation?
A: Yes. Industrial models have bleed-off valves to fine-tune nitrogen pressure and traction force on site.
Q3: What is the recommended mounting method?
A: Rod-down installation is recommended for seal lubrication and longer service life; horizontal mounting is also supported for lubricated models.
Q4: When does the gas spring need replacement?
A: Reduced retraction speed and oil residue on the rod indicate seal wear and gas leakage—replace promptly.
Q5: What is the MOQ and high-temperature adaptability?
A: Standard MOQ is 50 PCS. Standard units work up to +80℃; upgraded seals support higher temperatures.
