The 300N gas strut is a versatile nitrogen gas spring designed to exert a precise force of 300 Newtons (approx. 30kg / 67lbs). It is the ideal lifting solution for medium-weight applications such as large cabinet doors, heavy toolboxes, machine covers, and automotive bonnets.
Colewell's gas spring 300n series features a durable QPQ nitriding rod and a high-quality sealing system, ensuring smooth, controlled motion and a service life exceeding 50,000 cycles. We offer fully customizable lengths and end fittings to perfectly match your installation requirements.
| Force Rating | 300N (Newton) ≈ 30kg. Can be fine-tuned ±5% via release valve. Ideal for medium loads. |
| Material Build | Cylinder: Black Painted Steel or Stainless Steel (SS304/SS316). Rod: Hard Chrome Plated or QPQ Nitriding (Rust-proof). |
| Sealing System | High-quality Fluororubber seals prevent gas leakage and dust entry, ensuring the gas spring 300n maintains pressure over time. |
| Operating Temp | Standard: -20℃ ~ +80℃ Extreme: -40℃ ~ +120℃ (Custom Model). |
Mounting: We offer both Compression (Lift) and Tension (Pull) types. Install with the rod facing down for optimal lubrication.
Stroke Margin: Always reserve a 10%~20% stroke margin to prevent bottoming out. For robotic arms, choose our high-response models.
ISO 9001 & TS 16949 certified. RoHS compliant materials ensure no harmful gas release, protecting air quality.
• Joints: Standard Ball studs, Forks, or Eyelets.
• Force: Precise calculation based on your door weight.
• Finish: Custom colors to match your equipment.
Lifting & Tilting: Perfect for lifting heavy protective covers, access doors, or maintenance hatches on industrial machinery (approx. 30kg load).
Controlled Motion: Provides smooth, damped opening and closing for heavy oven doors, commercial freezers, or tanning beds.
Built-in hydraulic damping provides steady force for lifting and lowering, preventing slamming.
Constructed from high-quality steel or stainless steel for long-lasting performance in industrial environments.
QPQ or powder coating ensures the 300N gas strut resists rust and wear.
Available in various lengths and strokes to fit your specific gas spring 300n application.
Comes with diverse mounting brackets (ball joints, eyelets) for quick setup.
Self-contained nitrogen system requires no external power or refilling.
