Product Lineup

Gas Springs – Fixed Force

High quality American Made 316 stainless steel fixed force gas springs are self-contained pneumatic devices capable of producing very large forces. Each gas spring is pressurized with nitrogen gas and contains a small amount of lubricating oil within the cylinder. These gas springs not only have a superior visual appearance and quality, they are also available in various stroke lengths and forces. Used in opening or closing apparatus either by a vertical or horizontal travel for lifting, counterbalancing and motion control of doors, hatches, safety lids, hoods, cargo doors and access panels. Ameritool gas springs are suitable for all purposes and have unlimited application possibilities. Gas spring components are in stock and ready for immediate assembly and quick turnaround.

Our industrial grade 316 stainless steel adjustable force gas springs are a powerhouse capable of lifting up to 1200 Lbs. There are no tools required; it just provides trouble free and practical support for years. Gas spring components are in stock and ready for immediate assembly.

Gas Springs – Carbon

Ameritool offers a wide variety of Nitride coated steel gas springs. Gas springs provide a controlled opening force, making them ideal for lids, doors and hatches that need assistance opening up. The below chart shows Ameritool gas springs are available in many sizes and forces. Gas springs are also known as gas struts, gas props, gas pistons or gas lifts.

Gas Springs – Tension

Tension gas springs also known as reverse acting gas springs are constructed from 316 stainless steel. The force on these springs pulls the piston rod inward, operating in the opposite direction of other gas springs. Great for use on doors, lids, hatches and hoods that need to stay closed. In its relaxed state, the spring is compressed; you must pull to extend it. Temperature range is -40° to +300° F.


There are three types of dampers: extension, compression and dual direction. Extension dampers provide controlled speed while the rod is being extended out of the tube. Compression dampers provide a controlled speed while the rod is being compressed back into the tube. Dual rate dampers have equal amount of damping in both directions. Dampers are designed in particular to match each individual application.

Tension Springs – Adjustable Force

Ameritool Adjustable Force Tension Springs are made from 316 stainless steel. Just like the adjustable force gas springs the pressure on these can be reduced down by the user with no tools required. The force on these springs pulls the piston rod inward, operating in the opposite direction of standard gas springs. Great for use on doors, lids, hatches and hoods that need to stay closed or would use assistance while closing. In its relaxed state, the spring is compressed, you must pull to extend.
