✅ Slow Motion Control: Hydraulic damping ensures smooth, steady opening and closing, preventing sudden drops.
✅ Heavy Duty Support: Adjustable force (50N-3000N) handles heavy hoods and industrial covers with ease.
✅ Safety Protection: Eliminates the risk of lid slamming, protecting operators and expensive equipment.
✅ All-Weather Durability: QPQ treated rod and premium seals perform reliably in extreme heat or cold (-40°C to +80°C).
The Slow Speed Hydraulic Force Hood Damper is an advanced motion control device designed to eliminate the dangers of free-falling lids and snapping hoods. By integrating a specialized hydraulic oil circuit, this damper regulates the speed of extension and compression, ensuring a smooth, steady movement throughout the entire stroke.
Unlike standard gas springs that may accelerate rapidly, our hydraulic dampers provide constant resistance. This makes them indispensable for heavy automotive hoods, delicate industrial machinery covers, and access panels where safety and controlled operation are paramount.
| Damping Force | 50N - 3000N. Customizable resistance to match the weight of the hood, ensuring it doesn't drop too fast or require excessive force to lift. |
| Motion Control | Slow Speed Technology: Hydraulic fluid restricts piston speed, creating a safety buffer against gravity. Ideal for heavy lids. |
| Material Build | Cylinder: Heavy-gauge Steel with black powder coating. Rod: QPQ Nitrided Steel for superior wear and corrosion resistance. |
| Operating Temp | Standard: -20℃ to +80℃. High-viscosity oil options available for consistent damping in extreme heat (engine bays). |
Standard springs can cause lids to fly open, potentially damaging hinges or injuring users. Our slow speed dampers manage this energy, providing a premium, luxurious opening feel.
Available in extension damping (resists opening), compression damping (resists closing), or both, giving you total control over lid movement.
ISO 9001 & TS 16949 compliant. Manufactured to meet rigorous automotive industry standards for lifecycle and safety.
• Connections: Ball joints, eyelets, or custom brackets.
• Speed: We can tune the damping orifice to achieve your desired opening/closing time (e.g., 3 seconds vs. 10 seconds).
Premium Lift: Provides a high-end feel for engine hoods. The slow opening prevents the hood from bouncing at the top of the stroke.
Safety Guards: Heavy protective covers on CNC machines or generators can be dangerous. Hydraulic dampers ensure they close slowly and safely.
Access Doors: Controls the movement of large side access panels on buses and trucks, preventing wind damage and injury.
Lid Stay: Prevents heavy steel lids from slamming shut on fingers, making daily tool access safer and quieter.
Hydraulic fluid regulates piston speed, ensuring slow, steady movement every time.
We adjust the internal pressure to match the exact weight of your hood or lid.
Prevents sudden slamming, protecting operators from injury and equipment from damage.
Corrosion-resistant QPQ rod and steel body ensure reliable performance outdoors.
Hydraulic damping minimizes operational noise, ideal for quiet environments.
Sealed hydraulic system requires no external lubrication or servicing.
