Also referred to as traction gas struts or pulling gas springs, these units operate in the direction opposite of compression gas springs. Mounting constraints often do not allow for the use of compression springs; i.e., 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 often function as tensioners on mechanical assemblies and belt drives.

JUTENG Gas Springs supplies a complete range of tension gas springs. JUTENG can also provide custom-built tension springs in various rod, tube, and material configurations. The following matrix outlines the various rod & tube combinations, force characteristics and dimensional parameters available as a custom-built tension spring.
