How to Select the Right Gas Spring for Your Application
Gas springs (also known as gas struts or gas dampers) are essential components used to provide smooth, controlled, and safe motion in a wide range of applications, including automotive, architectural doors, furniture, medical equipment, and industrial machinery.
Selecting the right gas spring requires careful consideration of the following factors.
1. Force
The required force (measured in Newtons) depends on the weight of the object being supported, its center of gravity, and the mounting geometry.
Higher force is typically required for automotive hoods and tailgates, while lower force is suitable for office furniture and lightweight equipment.
2. Stroke Length
Stroke length is the distance the piston rod travels during operation.
It should be selected according to the required opening angle, lifting height, or range of movement.
- Short stroke: Compact covers and hatches
- Long stroke: Medical beds and large access panels
3. Mounting Configuration
Selecting the proper mounting configuration ensures smooth operation and long service life.
- End Mounting – Ideal for linear motion applications
- Side Mounting – Suitable for equipment with limited installation space
- Clevis Mounting – Recommended when installation flexibility and angular movement are required
4. Operating Environment
Environmental conditions should always be considered, including temperature, humidity, corrosion, dust, and vibration.
For marine, outdoor, or corrosive environments, stainless steel gas springs or corrosion-resistant coatings are recommended.
5. Temperature & Load Compensation
Applications exposed to significant temperature fluctuations or varying loads may require temperature-compensated or load-compensated gas springs to ensure consistent operating performance.
6. Sealing & Safety
High-quality sealing is essential to prevent gas leakage and maintain long-term performance.
For safety-critical applications such as automotive and medical equipment, gas springs equipped with pressure relief or safety features are recommended.
7. Custom Design Requirements
When standard products cannot satisfy the required force, stroke, dimensions, or mounting configuration, a custom-designed gas spring provides the most effective solution.
The KGS Advantage
KGS Co., Ltd. employs advanced automated manufacturing systems throughout its key production processes to achieve precise machining and superior surface finishing.
Every gas spring undergoes repeated cycle testing under simulated operating conditions to detect hidden defects such as sticking, abnormal noise, and initial force reduction before shipment.
This rigorous quality control process ensures dependable performance in demanding automotive, medical, and industrial applications.
KGS also provides complete OEM and ODM engineering services. Simply provide the required force, stroke length, mounting configuration, performance specifications, or CAD drawings, and our engineering team will develop a customized gas spring solution tailored to your application quickly and efficiently.
