Traction Gas Spring
Shuangyuan produce a complete range of tension gas springs. Sometimes referred to as traction springs, these units operate the opposite of compression gas springs. They retract rather than extend. Mounting constraints often do not allow for the use of compression springs. Examples include doors and access panels hinged horizontally at the bottom and any type of cover or lid that must be pulled open or pulled shut. Tension gas springs also find many uses as tensioners on mechanical assemblies and belt drives. In order to accommodate a wide range of force and stroke requirements, Shuangyuan offers these units in mild steel in a number of sizes.
| Size | Stroke Range | Force Range | K-Factor | Extended Length | Materials |
| 6/15 | 30–300 mm | 100-600 N | 1.55 | 2*Stroke+85mm | Steel/Stainless |
| 8/18 | 30–400 mm | 200-1000 N | 1.60 | 2*Stroke+85mm | Steel/Stainless |
| 10/22 | 30–500 mm | 300-1500 N | 1.60 | 2*Stroke+100mm | Steel/Stainless |
| 14/28 | 50–500 mm | 500-2500 N | 1.70 | 2*Stroke+100mm | Steel/Stainless |
