Kinematics vs. Industry

Interactive By-Motion Mechanism Finder

Whether you are building a specialty marine hatch, an outdoor kiosk, or a clinical workstation, your gas spring specification is governed by hinge kinematics. Select how your assembly moves below to see the exact load behavior and series match.

NTZ Damped Extension

Gravity pulls the lid closed; the gas strut crosses the moment arm to lift and hydraulically brake the final degrees of travel.

Primary: NTZ & NTF Series 15 to 2,000 N 40 to 450 mm Stroke

Top-Hinged Upward Lids & Canopies

In overhead lids, vehicle tailgates, CNC guards, and marine hatches, gravity pulls the panel shut while the effective lever arm shortens as the lid rises. Standard undamped cylinders can accelerate into the upper mechanical stop and stress the hinges.

Kinematic Requirement End-of-stroke hydraulic oil damping (NTZ) prevents hinge slam at full extension.
Cross-Industry Examples SUV liftgates, flip-up kitchen cabinets, CNC enclosures, aircraft bins, trailer canopies.
View NTF / NTZ Series
NTA Rigid Pull-Lock

As the panel folds down toward the user, applied surface weight pulls outward in tension on the piston rod.

Primary: NTA Series (or Tension) 50 to 1,250 N 10 to 500 mm Stroke

Bottom-Hinged Drop-Down Panels & Fold-Down Tables

When a panel hinges at the bottom and folds downward toward the operator, gravity assists opening rather than closing. Once deployed horizontally, any weight placed on the surface tries to pull the piston rod outward in extension.

Kinematic Requirement Controlled downward deceleration or NTA rigid extension locking to hold level under load.
Cross-Industry Examples Rail and truck cab fold-down tables, sleeper bunks, drop-down ramps, Murphy beds, service doors.
View NTA Series
NTG Elastic / NTA Rigid

Lower pivot geometry converts upper torso or frame torque into axial compression or tension along the locking strut.

Primary: NTG & NTA Series 50 to 1,250 N Lever or Bowden Cable

Pivoting Backrests & Articulated Tilt Frames

Mechanisms rotating around a lower pivot pin experience dynamic load reversals as user posture or frame angle shifts. Depending on whether the application prioritizes ergonomic shock absorption or zero-deflection clinical support, we pair the pivot with elastic or oil-rigid locking.

Kinematic Requirement Stepless bidirectional locking with cushioned bounce (NTG) or rigid pull-locking (NTA).
Cross-Industry Examples Office and passenger seats, hospital bed Fowler backrests, recliners, tilting assembly fixtures.
View NTG Series
NTC / NTB

Axial guide rails absorb side-loads while an internal NTC double-tube or NTB single-tube cylinder locks height rigidly.

Primary: NTC (2-Tube) & NTB (1-Tube) 50 to 500 N Up to 500 mm Travel

Vertical Telescoping Columns & Pedestals

Assemblies moving straight up and down inside a linear guide column require two critical properties: strict protection against eccentric side-loads and a flat force curve (low $k$-ratio) so the operator does not have to fight excessive upward force at the bottom of the stroke.

Kinematic Requirement Rigid compression locking with maximum stroke-to-cylinder efficiency (NTC double-tube).
Cross-Industry Examples Point-of-care medical carts, overbed tables, standing desks, marine helm pedestals, podiums.
View NTC Series
Zero-Gravity Four-Bar Balance

Diagonal strut placement inside a four-bar parallelogram matches the changing cosine torque curve across the arc.

Primary: Custom NTF / NTZ or NTA Low Friction Seals Tuned K-Ratio

Counterbalanced Pantograph & Four-Bar Linkages

Multi-link parallelogram arms carry payloads whose effective torque changes non-linearly with the cosine of the arm angle. By tuning the pivot coordinates, gas volume ($k$-ratio), and low-friction seal package ($F_R$), the payload floats weightlessly at any height.

Kinematic Requirement Matched spring-rate progression ($F_2 / F_1$) and low breakaway friction for “zero-gravity” float.
Cross-Industry Examples Surgical lighting and X-ray arms, heavy display booms, industrial tool balancers, pantograph doors.

Engineering Selection Guide

Match Your Application Load Direction to the Right Series

Every OEM mechanism comes down to two questions: does the assembly need to lock mid-stroke, and which direction does the external load push or pull on the piston rod?

Controlled Motion + Automatic Feel = Motion-Matic

Internal nitrogen charge supplies the lifting force, while hydraulic oil and valve geometry control whether the rod glides to a damped stop, cushions with elastic give, or locks rock-solid against tension or compression.

Engineering FAQs

Application & Sizing Questions

How do I choose between elastic locking, rigid locking, and non-locking lift gas springs?

Match the cylinder to how your mechanism moves and supports load. Choose NTG elastic locking gas springs when the user needs stepless positioning with a gentle, shock-absorbing cushion, such as office, automotive, aircraft, or train seats. Choose NTA, NTB, or NTC rigid oil-locking struts when the locked assembly cannot tolerate bounce, such as hospital beds, surgical tables, standing desks, or tilting workbenches. Choose NTF or NTZ compression gas springs when a hood, cabinet lid, overhead bin, or machine guard simply lifts open to a fixed stop.

Should I specify extension rigid locking (NTA) or compression rigid locking (NTB / NTC)?

Follow the direction the external load acts on the piston rod while locked. If weight tries to pull the piston rod outward, such as a raised hospital bed backrest, recliner sofa back, or fold-down cabin table, specify NTA rigid extension locking (50 to 1,250 N). If weight pushes downward to compress the rod inward, such as a standing desk, examination table, or press fixture, specify single-tube NTB (20 to 350 mm stroke, 50 to 500 N) or double-tube NTC (50 to 500 mm stroke, 70 to 450 N).

When should I choose a double-tube NTC locking spring over a single-tube NTB spring?

Both NTB and NTC lock rigidly in compression under downward loads. Specify the twin-tube NTC series when your design requires a longer stroke relative to the installed cylinder length (50 to 500 mm travel) and a lower spring-rate force increase, such as telescoping mobile medical carts, overbed tables, and railway sleeper berths.

What industry compliance, washdown, and duty-cycle benchmarks can Newton gas springs support?

We configure cylinders and materials around your regulatory and environmental requirements, including medical disinfectant wipe-down resistance and CPR mechanical override readiness, aerospace and rail cabin interior standards (such as FAR 25.853, EN 45545, and NFPA 130 alignment), ASTM B117 salt-spray corrosion resistance with 304 or 316 stainless steel for marine and food-processing washdowns, and high-cycle fatigue testing aligned with BIFMA furniture benchmarks.

Can Newton calculate the required gas spring force and mounting points from our CAD drawing?

Yes. Share your panel or assembly weight, center of gravity distance from the hinge pivot, desired opening angle or travel, and available mounting space. You can use the Quick Pre-Check Calculator above or submit your specs on our custom gas springs page, and our engineers will return a complete force calculation and quote within 24 hours.
