Demanding applications require uncompromising stability. Colewell Rigid Lockable Compression Gas Struts provide immovable support the moment the valve is closed. Unlike elastic locking springs that have a slight "bounce," our rigid locking gas struts use a unique oil-chamber design to ensure zero drift in the compression direction.
This makes them the industry standard for medical examination tables, heavy treatment chairs, and industrial machinery where maintaining a fixed position under heavy load is critical for safety and precision.
| Locking Force | 100N - 5000N. High locking force capabilities ensure the strut stays rigid even under extreme weight loads. |
| Locking Direction | Rigid in Compression: Solid lock when pushing in (e.g., sitting on a bed). Rigid in Extension: Solid lock when pulling out (optional). |
| Material Build | Cylinder: Steel (Black Powder Coated) or Stainless Steel 304/316 for medical hygiene. Rod: Hard Chrome Plated for durability. |
| Operating Temp | Standard: -30℃ ~ +80℃. Specialized seals available for high-temp sterilization environments. |
Our rigid locking models use oil to block the piston, creating a solid column of steel-like strength. This prevents the "spongy" feel of gas-only locking springs.
Optional internal relief valves allow the strut to yield under extreme overload, preventing structural damage to the application (e.g., if a hospital bed is forced down).
ISO 9001 & IATF 16949 certified. Meets medical industry standards for safety and reliability.
• Release Systems: Lever actuation, Bowden cables, or hydraulic release.
• Size: Customizable rod/tube diameters (e.g., 8/22, 10/22, 10/28).

Zero-Bounce Support: Ensures examination tables and backrests remain absolutely rock-steady when a patient sits or lies down.

Precise Adjustment: Used for adjusting heavy steering columns, control panels, or safety guards where vibration-proof locking is required.

Oil-based locking eliminates the sponge effect found in gas-only springs.

Supports static loads up to 10,000N when locked, ensuring absolute safety.

Fail-safe design prevents accidental release or collapse under load.

Requires minimal force to actuate the release pin, ensuring user-friendly operation.

Advanced sealing technology ensures performance for over 50,000 actuations.

We engineer specific force curves and locking behaviors for your OEM needs.

Colewell delivers high-performance rigid locking gas struts that meet the strictest safety standards.
Our expertise in rigid locking technology ensures that medical devices and industrial machinery operate with absolute stability and zero drift.
A: Rigid locking (oil-based) acts like a solid column with zero movement, ideal for medical tables. Elastic locking (gas-based) provides a slight "cushioning" effect, better for passenger seats.
A: By depressing the release pin at the rod end. This can be done via a lever, push-button, or Bowden cable system (we supply compatible releases).
A: No. Our rigid locking struts feature internal safety valves. Even if overloaded, they are designed to yield slowly rather than collapse, ensuring operator safety.
A: For rigid locking performance, the piston rod should generally point downwards. However, specific oil-chamber designs allow for variable orientation. Consult our engineers for details.
