Where We Fit
One Aircraft Cabin, Five Ways to Move
Every passenger seat, stowage bin, and fuselage door moves under distinct loads. Here is where each aerospace gas strut and aircraft interior locking gas spring does the work.
Passenger and Crew Seat Recline
Infinite-position aircraft seat gas spring with cushioned elastic locking that absorbs in-flight turbulence.
Business Class Lie-Flat Suites
Oil-locked aircraft interior locking gas springs that hold rigid in extension for lie-flat beds and tables.
Adjustable Calf and Leg Rests
Compression-locking aviation gas springs that lock solid under downward leg loads without drifting down.
Overhead Luggage Bins
Oil-damped overhead bin gas struts that assist heavy carry-on doors upward and brake softly at full open.
Aircraft Cabin Doors and Hatches
High-force aircraft cabin door gas struts for smooth boarding door counterbalance, avionics bays, and hatches.
Choose Your Series
Pick the Aviation Spring by How the Part Moves
Ask two questions: should it lock in position, and which way does the passenger or door load push? The answers point to one of five aerospace gas spring series.
| Series | Best For | Locking and Motion | Force (F1) | Stroke | Product Page |
|---|---|---|---|---|---|
| NTG | Economy and crew seat recline | Elastic (both directions) | 11 to 225 lbf (50 to 1,000 N) | 0.4 to 19.7 in (10 to 500 mm) | View NTG |
| NTA | Business class lie-flat seats, tables | Rigid in extension | 11 to 281 lbf (50 to 1,250 N) | 0.4 to 19.7 in (10 to 500 mm) | View NTA |
| NTB | Premium economy calf and leg rests | Rigid in compression | 11 to 112 lbf (50 to 500 N) | 0.8 to 13.8 in (20 to 350 mm) | View NTB |
| NTZ | Overhead luggage bins, galley doors | Damped lift | 3.4 to 450 lbf (15 to 2,000 N) | 1.6 to 17.7 in (40 to 450 mm) | Quote NTZ |
| NTF | Aircraft cabin doors, avionics hatches | Free lift | 3.4 to 450 lbf (15 to 2,000 N) | 1.6 to 17.7 in (40 to 450 mm) | Quote NTF |
Inside the Cylinder
Nitrogen Lifts and Oil Controls
Every Newton aviation gas spring is charged with high-purity nitrogen to deliver smooth, repeatable extension force. Internal hydraulic oil governs how that force behaves: in NTZ overhead bin gas struts it acts as a quiet end-of-travel brake, while in NTA and NTB aircraft interior locking gas springs it locks the piston rod rigid. NTG holds against compressed nitrogen instead, giving passenger seatbacks a gentle, cushioned feel during turbulence.
Engineered for Flight Profiles: From sub-zero tarmac turnarounds to pressurized cabin cruise, we calibrate gas charge and seal geometry so every aerospace gas strut performs consistently across thousands of flight cycles.
Make It Yours
Sized, Finished and Fitted to Your Envelope
Once the series is selected, custom dimensions make it fit tight seat frames and fuselage envelopes. Rods run from 0.16 to 0.47 in (4 to 12 mm), and cylinders from 2.4 to 25.6 in (60 to 650 mm) long.
Corrosion-Resistant Finishes
Black and Chrome on every series, plus Silver Gray, White, and Light Gray to match cabin trim.
Custom Aviation End Fittings
Single-ear eyelets for compact seat linkages, or double-ear clevis fittings for overhead bins and doors.
Cable Release Actuators
Low-effort Bowden cable and lever release heads let armrest buttons unlock seat springs smoothly.
How We Work
From First Sample to OEM Production
Three straightforward steps from your aircraft seat or cabin interior CAD model to force-tested production batches.
-
Share Your Envelope
Send a CAD file, drawing, or part number with component weight, center of gravity, and pivot coordinates.
-
Validate Prototype Samples
We build custom prototype samples to your exact Newton force, stroke, and release spec for rig testing.
-
Scale to Aviation OEM Supply
Every production batch is 100% force-verified so every shipset matches your approved master sample.

Aerospace and Aircraft Gas Springs
Custom aircraft seat gas springs, overhead bin gas struts, and cabin door struts from 15 to 2,000 N.
NTG, NTA or NTB: which aircraft seat locking gas spring do I need?
NTG provides a cushioned elastic lock ideal for passenger and crew seat recline. NTA locks rigid against extension forces on lie-flat beds and fold-down tables, while NTB locks rigid against compression loads on adjustable calf rests and leg rests.
How do overhead bin gas struts prevent cabin doors from slamming?
Our NTZ overhead bin gas struts use calibrated internal hydraulic oil damping to slow the final degrees of opening and closing travel, protecting hinges and keeping stowage compartments quiet.
How do you size an aircraft cabin door gas strut or seat spring?
Send us your door or seat back weight, center of gravity, and hinge coordinates. Our engineers calculate the exact F1 force and verify performance across cold ground operations and pressurized cabin temperatures.
How fast can aviation OEMs get prototype samples?
We confirm prototype lead times with your quote. Every sample is built to your full force, stroke, and end-fitting specification, or reverse-engineered to match an existing aircraft strut.
