Colewell's Lockable Gas Pressure Spring series combines the lifting power of a gas strut with the precision of a mechanical lock. By actuating a release pin, users can stop the piston rod at any position along the stroke, making it indispensable for adjustable hospital beds, ergonomic desks, and passenger seats.
Additionally, our Adjustable Gas Springs feature a built-in release valve. This allows installers to safely release nitrogen gas to fine-tune the force on-site, ensuring perfect balance for prototypes or variable loads without needing to order new parts.
| Force Range | 50N - 1000N. Lockable: Fixed force with locking capability. Adjustable: Force can be decreased via valve (e.g., ship at 500N, adjust down to 350N). |
| Locking Types | Elastic Locking: Cushioned feel (ideal for chairs). Rigid Locking: No movement when locked (ideal for medical tables). |
| Material Build | Cylinder: Steel (Black/Silver) or Stainless Steel 304/316. Rod: Hard Chrome Plated or QPQ Nitriding. |
| Operating Temp | Standard: -30℃ ~ +80℃. Includes special internal valves for reliable locking in extreme conditions. |
A release pin at the end of the piston rod controls an internal valve. When pressed, the spring moves; when released, the valve closes, locking the spring in place instantly.
For adjustable gas springs, a built-in grub screw allows you to release gas safely. This is perfect for prototyping when the exact force requirement is unknown.
ISO 9001 certified. Locking mechanisms are cycle-tested to ensure safety and reliability in critical medical and industrial applications.
• Release Systems: Compatible with levers, Bowden cables, and push-buttons.
• Size: Custom stroke lengths for specific ergonomic designs.
Backrest Adjustment:Rigid locking gas springs hold hospital bed backrests firmly in place, ensuring patient safety and comfort at any angle.
Adjustable Desks & Chairs: Allows smooth height and tilt adjustment. Elastic locking models provide a comfortable "bounce" for seating applications.
Unique valve design allows you to release gas to fine-tune the force for a perfect balance.
Stop the piston at any point in the stroke for precise positioning control.
Rigid locking models can withstand high loads in either compression or tension direction.
Space-saving cylinder design fits seamlessly into chair bases and medical table columns.
Premium steel construction and seals ensure longevity even with frequent adjustments.
Sealed system requires no external lubrication or maintenance throughout its life.
Colewell Machinery leads the way in functional gas spring technology. Our lockable and adjustable gas springs offer unparalleled flexibility for designers and engineers.
Whether you need rigid locking for safety or on-site adjustability for convenience, our R&D team delivers precision solutions tailored to your needs.
