Calculating Gas Spring & Strut Size & Length

Industrial Gas Springs provides a valuable service offering the production of non-stock or custom compression gas springs to meet specific requirements.

If you have a specific size and force of gas spring you need you can enter those dimensions here and either request a quote or request a gas spring prototype be provided.

Gas Springs When Extended vs. Compressed

A wide range of lengths and sizes can be supplied. There is a limit to how short a fully extended gas spring, prop, or lift can be made in relation to the stroke. The minimum extended shoulder length is calculated by referring to the following table and then making a simple calculation. To calculate gas spring size: multiply stroke by two and add the appropriate factor from the table (all dimensions in inches). 2 x Stroke plus Standard Factor below = minimum shoulder length (not including end fittings). Before requesting a quote or prototype you can check if your dimensions fall within our minimum sizes. Even if they don’t we still have options we can offer or may be able to find a way to make a standard size work. Contact IGS(link to Contact Us, button?) for more details.

Type 4 0.95" N/A N/A
Type 6 1.24" 2.14" 2.54"
Type 8 1.51" 2.53" 3.08"
Type 10 1.85" 2.68" 3.27"
Type 14 2.04" 2.79" 3.93"
Type 20 3.35" 3.35" 5.68"

This calculation yields the extended shoulder length of the gas spring. To determine the extended length with fittings, add the “A” dimension of the each end fitting selected from the Gas Spring Fittings table.
