How Pull Gas Struts Work

Understanding how pull gas struts work helps users choose better motion solutions. Therefore this topic matters for engineers, buyers, and DIY users. However many users only know about push type gas springs. A pull gas strut works the opposite way. It generates force during inward rod movement. Therefore it is perfect for controlled closing and assisted pulling applications.

Pull gas struts, also called tension or traction gas springs, work opposite to compression types. Their piston rod stays inside the cylinder at rest, and when extended, internal gas force pulls the rod back. This makes them ideal for lids, hatches, ramps, stairways, and trailer doors that fall downward and need controlled closing and assisted return. They also suit doors or covers hinged at the bottom and can act as tensioners on mechanical assemblies and belt drives. GASTAC supplies a full range of these pull type solutions.

Pull gas struts work by generating force during inward rod movement rather than outward push. At rest, the piston rod sits inside the cylinder. When users extend the rod, the internal gas compresses and creates tension. After release, the gas force pulls the rod back inward. This reverse action provides controlled closing, smooth

Gas struts that pull instead of push are called pull gas struts, tension gas springs, or traction gas struts. Unlike compression types that extend outward, these units retract the piston rod back into the cylinder. This creates controlled inward force, making them ideal for lids, hatches, ramps, and panels that need assisted closing or downward motion support.

GASTAC is a gas spring manufacturer with strong engineering experience. We produce pull type gas struts in standard and custom specifications. Our cylinders use high quality tubes and seals. Therefore the performance stays stable under long cycles. Moreover we offer corrosion resistant finishes for harsh environments. Automotive, marine, medical, and industrial buyers trust our production processes.

GASTAC supplies a complete range of tension gas springs. GASTAC 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 gas spring.

GASTAC provides standard pull gas struts in a wide range of specifications based on Rod Ø, Body Ø, Stroke, Extended Length, and Force (lbs). Customers can select matching dimensions and force levels to fit different mounting spaces, motion needs, and load requirements. This makes GASTAC suitable for both OEM projects and replacement applications across various industries.

Users must check stroke, force, and extended length. Moreover installation method and mounting style matter. Therefore buyers should confirm hinge geometry and load direction. GASTAC provides technical support to speed up selection. We help OEM clients and small batch buyers. Because correct sizing improves performance and safety.
