● Extended Length 200mm – 900mm
● Stroke Length 100mm – 500mm (customizable)）
● Gas springs are widely used in storage beds that feature a lift-up or gas-assisted lifting mechanism. These springs help raise the bed base, providing access to a storage compartment underneath without the need for excessive force, making it easier to store items.

● Extended Length 200mm – 900mm
● Stroke Length 100mm – 500mm (customizable)
● Consider how far the cupboard door will open. Gas springs with different stroke lengths provide different opening ranges. For wide-opening cupboard doors, a longer stroke may be required.

✅ Effortless Lifting: Powerful hydraulic assistance makes lifting heavy mattresses (up to 150kg) feel weightless.

● Stroke: 150-350mm
● Adjustable Viewing Angle – Gas springs enable easy tilting or swiveling of the TV, allowing for optimal viewing angles without the need for manual adjustment.
● Safety Mechanism – Many gas springs for TV mounts come with built-in safety features, such as locking mechanisms that hold the TV securely in place when in the desired position, preventing accidental drops.

✅ Direct Replacement: Fits popular rolling cabinets (Craftsman, Snap-on, Husky) & truck bed boxes.

✅ Heavy Duty Lift: High-pressure nitrogen handles heavy steel lids; prevents accidental dropping.

✅ Workshop Ready: Black Nitride rod & NBR seals resist grease, oil, and grime common in garages.

✅ Soft-Open Action: Controls the lid's upward momentum, preventing it from banging against the back hinge.

● For toy box lids, common stroke lengths range from 150mm to 300mm, depending on how much lid movement is desired. Longer strokes are typically needed for larger toy boxes with bigger lids.

● Determine how far you want the lid to open. Common lid opening angles are between 75° to 90°, but this can vary depending on your specific needs. For a larger opening, you may need a longer stroke length or multiple gas struts.

● Gas Strut Diameter

The diameter of the gas strut is usually proportional to the load it supports. For example, a standard 8mm or 10mm diameter is commonly used for toy box lids, but larger models may require a 12mm diameter.

● End Fittings: Available with eyelets, ball joints, brackets, or custom fittings for secure mounting
● 100-1500mm (distance the rod extends)
● Nitrogen gas for smooth and controlled operation

● Optimize bed functions to ensure safety, convenience and durability
● The hydraulic lifting gas springs for beds we provide are designed specifically for bed structures to help bed covers rise and fall smoothly and easily. It can effectively support the weight of the bed, ensure the stability of the bed cover when it is opened, and provide strong rebound force to ensure the safety and stability of the bed cover when it is closed. The products are widely used in furniture designs such as bed frames, storage beds, and lifting beds, especially for furniture manufacturers who purchase in bulk to ensure uniformity and stability of quality in large-scale production.
