Pneumatic Damper / Damping Gas Spring
Support Heavy Covers with Controlled Soft Stop
Combine lifting support with soft-stop damping for safer, quieter lids, access panels, and machine doors.
- Support force + soft-stop control in one component.
- Custom damping for non-standard mounting layouts.
- Application guidance and OEM sample support.
What is a Pneumatic Damper?
A standard gas spring provides uniform lift force, but a pneumatic damper adds an oil zone to slow the piston rod noticeably near the end of travel.
- Support & Damping: Lift assistance plus a controlled close in one assembly.
- Safer Operation: Reduces slam, impact load, and user risk for heavy panels.
- Customizable: Engineer custom dual-damping or non-standard rod directions based on your layout.
Stroke Motion Characteristics
Understand the damping behavior across the entire travel distance, including the free travel zone and soft-stop zone.
Key Technical Features
Engineered for real-world constraints where off-the-shelf damping isn't enough.
Soft-Stop Lift
Combines support force with end-of-stroke deceleration for safer lids.
Rod-Down Damping
Optimized oil zone designed for standard downward rod installation.
Two-Way Damping
Custom force curves for non-standard mounting or both-side motion control.

Fast Selection Factors
Provide these inputs to shorten the quote cycle and improve accuracy.
- Load & Stroke: Define lid weight, center of gravity, and actual travel distance.
- Mounting Direction: Rod-down is standard; custom orientation available.
- Target Speed: Choose between gentle assist and strong soft-stop.
- Damping Need: End-of-stroke, free travel, or controlled both sides.
- Environment: Temperature and frequency affect seal and oil choices.
Typical Applications
Ideal for environments where support alone is not enough and human interaction requires a refined feel.
- Industrial Covers: Prevent heavy maintenance covers from dropping.
- Electrical Cabinets: Soft-stop movement for inspection doors and service hatches.
- Furniture Lids: Premium feel for utility compartments and benches.
- Vehicle Compartments: Control access doors and hoods safely.
- Medical Equipment: Controlled movement in noise-sensitive settings.

Frequently Asked Questions
What is a pneumatic damper?
A pneumatic damper, also called a damping gas spring, combines gas spring support with damping control so a lid or cover lifts with assistance and closes with a softer stop.
Why does installation direction matter?
Standard end-of-stroke damping usually works best when the rod is installed downward, allowing the piston rod to pass through the oil damping zone correctly near the end of travel.
Can you provide rod-up or both-side damping solutions?
Yes. If your product requires a non-standard mounting direction or controlled damping on both sides of motion, we can develop a custom pneumatic damper solution.
What information is needed for fast selection?
Please share load, center of gravity, stroke, opening angle, installation space, target speed, temperature range, operating frequency and damping expectations. Our engineers then recommend the right force curve and mounting layout.
