Tension Springs: Engineering, Specification, and Selection Guide 2026
Tension springs are helical coils designed to resist a pulling force, providing a return mechanism or counterbalance in mechanical assemblies.
Tension springs are helical coils designed to resist a pulling force, providing a return mechanism or counterbalance in mechanical assemblies.
Selecting the correct gas spring requires precise force calculation, stroke measurement, and consideration of environmental operating temperatures.
Gas spring force is calculated using F = (W × D) / (2 × d), where W is lid weight, D is hinge-to-CG distance, and d is hinge-to-spring distance. Accurate inputs prevent undersizing or oversizing.
A gas spring damper is an internal mechanism that uses hydraulic oil to regulate the speed of the spring as it reaches the end of its extension travel.
Gas struts are self-contained nitrogen-charged cylinders used to provide controlled lifting, lowering, or holding force for hatches, lids, and machinery.
Stainless steel gas springs prevent component failure in high-corrosion environments by utilising 316 or 304 grade alloys instead of carbon steel.
Locking gas springs allow a lid, hatch, or equipment mount to be fixed at any point within its stroke range using a mechanical or hydraulic release.
Compression springs are open-coil helical springs that resist compressive force, providing the mechanical resistance needed for diverse industrial applications.
Gas springs are hydro-pneumatic lifting devices providing controlled extension force for industrial, automotive, and furniture applications.
This guide covers the technical parameters and material considerations for specifying industrial hardware, with a specific focus on high-cycle gas spring integration.
