What Are Heavy Duty Gas Springs?
Heavy duty gas springs are high strength gas springs designed to lift, support, balance, or control heavier components. They use compressed nitrogen inside a sealed cylinder to generate stable force, making large covers, machine guards, vehicle hatches, industrial seats, and heavy panels easier and safer to move.
Compared with standard gas springs, they usually have a larger rod diameter, stronger cylinder body, higher load capacity, and better durability, making them suitable for industrial equipment, vehicles, machinery, medical systems, and custom heavy load applications.
Heavy Duty Gas Springs Chart Size
When choosing a new gas spring or replacing an existing one, accurate measurement is essential.
①Begin by checking the rod diameter and body diameter, as these sizes affect the spring’s strength and load bearing ability.
②Then measure the stroke, which refers to how far the rod moves from the compressed position to the fully extended position.
③After that, measure the extended length, which is the full center to center distance between the two end fittings when the gas spring is fully open.
These measurements help confirm the right specification for your application and support smooth, dependable operation.
