How To Choose Gas Struts?

Gas struts, also known as gas springs or gas shocks, are essential components in various applications, providing controlled motion and support. Whether you're replacing old struts or selecting new ones for a specific project, understanding key factors can ensure you choose the right struts for your needs.


Understanding Gas Struts


Struts consist of a piston rod enclosed in a cylinder filled with compressed gas. They function by compressing the gas to create force, which helps in lifting, lowering, or supporting objects with controlled motion.


Identifying Your Requirements


Before selecting struts, determine the specific requirements of your application:

●     Load Capacity: Calculate the weight or force the strut needs to support. Ensure to account for any additional factors like dynamic loads or safety margins.

●     Stroke Length: Measure the distance the strut will need to travel between fully extended and fully compressed positions.

●     Mounting Orientation: Consider whether the strut will be mounted horizontally, vertically, or at an angle, as this can affect its performance.


Choosing the Right Size


Selecting the correct size of gas strut involves:

●     Rod Diameter: Larger rods typically offer higher load capacities but may require more space.

●     Cylinder Diameter: Determines the amount of gas and the force generated. Choose a cylinder diameter appropriate for your load requirements.


Understanding Compression Force


Compression force refers to the force exerted when the strut is compressed or extended. It's crucial to match the compression force of the strut with the weight of the object it will support.


Consider Environmental Factors


Environmental conditions can impact the performance and lifespan of gas struts:

●     Temperature Range: Choose struts rated for the temperature range they will operate in to prevent performance issues in extreme conditions.

●     Corrosion Resistance: If used outdoors or in corrosive environments, opt for struts with corrosion-resistant coatings or materials.


Safety and Quality Standards


Ensure the struts you choose comply with relevant safety and quality standards:

●     ISO Standards: Look for struts that meet ISO 9001 or ISO 14001 standards for quality management and environmental management.

●     CE Certification: Struts with CE marking indicate compliance with European Union safety standards.


Installation and Maintenance


Proper installation and maintenance prolong the lifespan and ensure optimal performance of struts:

●     Installation Angle: Follow manufacturer guidelines for mounting angles to avoid premature wear or failure.

●     Regular Inspection: Periodically inspect struts for leaks, wear, or loss of pressure, and replace as necessary to maintain safety and performance.


Gas struts play a crucial role in many industries, providing reliable support and controlled motion. Whether for automotive, industrial, or domestic use, making an informed choice ensures you get the most out of your struts.
