What Are Gas Struts and How Do They Work?
Gas struts, also known as gas springs or gas lifts, are mechanical devices used to lift, support, and control movement across a wide range of applications. They are commonly found in automotive, aerospace, furniture, medical, and industrial environments.
Thanks to their smooth and controlled operation, gas struts are ideal for applications where safety, precision, and reliability are essential.
How Gas Struts Work
At their core, gas struts consist of a sealed cylinder filled with pressurised gas and a piston rod that moves in and out of the cylinder.
When the strut is compressed or extended, the gas inside creates force that pushes or pulls the piston rod, generating a controlled lifting or supporting motion.
Key Benefits of Gas Struts
Gas struts offer several important advantages:
- Smooth and controlled movement
- Improved safety by preventing sudden drops
- Low maintenance operation
- Customisable force and size options
These features make gas struts suitable for both light-duty and heavy-duty applications.
Customisation and Versatility
Gas struts are highly versatile and can be customised to meet specific load and performance requirements.
Factors such as cylinder size, gas pressure, and piston design can be adjusted to create a strut tailored to a particular application.
Common Applications of Gas Struts
Gas struts are used across many industries and everyday products, including:
- Automotive – supporting car bonnets, boots, and tailgates
- Industrial equipment – lifting and positioning heavy machine components
- Doors and windows – enabling smooth opening and closing
- Furniture – recliners, adjustable chairs, and lift-up beds
- Medical equipment – hospital beds and examination tables
Conclusion
Gas struts are a versatile and reliable solution for lifting and motion control. Whether used in vehicles, furniture, machinery, or medical equipment, they provide a safe, controlled, and efficient way to manage movement and load support.
Frequently Asked Questions
What are gas struts used for?
Gas struts are used to lift, support, and control the movement of panels, lids, furniture, and mechanical components.
How do gas struts create lifting force?
Gas struts use pressurised gas inside a sealed cylinder to generate force that moves and supports a piston rod.
Are gas struts adjustable?
Some gas struts are adjustable, allowing force levels to be fine-tuned for specific applications.
Where are gas struts commonly used?
They are commonly used in automotive tailgates, furniture, industrial machinery, doors, and medical equipment.
