Land Stainless Locking Gas Springs combine lift assist with positive internal locking that holds at set positions until deliberately released. Built in AISI 304 or 316 stainless, with matching stainless end fittings, they deliver clean aesthetics and durable performance in marine, food, medical, and outdoor environments.
Construction and Materials
Gas cylinder and rod
AISI 304/316 stainless (polished rod for seal life); optional black-nitrided carbon steel versions on request.
End fittings & hardware
Stainless end fittings (ball sockets, studs, eyelets, clevis, brackets) for a fully corrosion-resistant assembly.
Seal system
High-integrity rod seals with a guided piston minimize friction, leakage, and side-load sensitivity.
Surface durability
Meets ASTM B117 neutral salt spray 500 hours (typical for 316 and treated components).*
Locking types
Rigid locking (zero-play feel) or elastic locking (micro-compliance for shock absorption).
Release options
Hand button, knob, or remote Bowden cable for safe off-axis actuation.
Performance and Adjustability
Force range
Position control
Motion quality
Consistency
Sizes and Interfaces
Common tube/rod sets
15 6, 18 8, 22 10, 28 14 mm.
Stroke options
~20–500 mm; extended length (C-C) per specification.
End fittings
10 mm/13 mm ball sockets, threaded studs M6 M8 M10, eyelets, clevis, stainless mounting brackets.
Documentation
Force curves, leak/pressure checks, cycle-life, and salt-spray data available.
Quality and Compliance
Manufactured by Land under IATF 16949 and ISO-certified systems with material traceability; RoHS/REACH-conscious options.
Installation Guidance
- Mount rod-down when possible to lubricate seals and extend life.
- Maintain axial alignment; use spherical joints to handle minor misalignment.
- Provide mechanical stops in hinges/brackets (the gas spring is not a travel stop).
- After installation, perform final force trim (adjustable models) to achieve target feel.
Applications
Land stainless locking gas springs-also known as locking gas struts, stainless locking gas lift supports, and stainless gas props-secure positions and prevent drift where corrosion resistance and hygiene matter.
Marine and Outdoor
Deck/cabin hatches, lockers, lazarettes, engine covers
Offshore and coastal equipment enclosures exposed to salt spray
Prefer 316 for aggressive marine conditions (backed by ASTM B117 500h performance)
Food, Medical, and Clean Facilities
Adjustable tables, carts, instrument arms, device covers
Wash-down enclosures and access doors where stainless and positive locking are required
Rigid locking variants prevent creep during procedures and calibration
Transportation and Vehicles
Hood, bonnet, trunk, boot, hatch, liftgate mechanisms requiring a locked position
RV/trailer compartments, utility bodies, service doors, toolboxes
Remote Bowden cable release for safe unlocking from a handle or console
Industrial Machinery and Automation
Machine guards and access panels that must hold at defined angles
Height-adjustable fixtures, HMI screens, test rigs with precise setpoints
Elastic locking versions add micro-compliance to absorb minor shocks
Need a fast recommendation from Land? Share environment (indoor/outdoor/wash-down/marine), preferred locking type (rigid or elastic), release mode (button/knob/cable), stroke and extended length (C-C), mounting space, estimated lid weight and hinge geometry. We will size the force window, damping, stainless grade, and stainless end fittings to match your build.
