Gas springs are mechanical marvels that have a wide range of applications, from everyday use in car hoods and office chairs to heavy industrial machinery. They provide controlled and reliable movement, making our lives easier and safer. Would you like to find out which gas spring is suitable for your situation? You can easily design the perfect gas spring with our guide. Use our configurator, calculator or replacement tool and order your gas spring online.
What is a gas spring?
A gas spring, also known as a gas strut or gas lift, is a device that uses compressed gas to exert force for lifting, lowering, and positioning objects. It consists of a cylinder, a piston, and a precise amount of compressed gas. When the piston is pushed, it compresses the gas, and the stored energy is used to generate force. Gas springs come in various shapes and sizes. Each design is meant for specific applications, ensuring smooth and controlled motion.
The science behind gas springs
Understanding the science behind gas springs is crucial to appreciating their functionality. These devices follow Pascal’s law, which states that in a confined fluid system, pressure applied at one point is transmitted undiminished throughout the fluid. In a gas spring, the confined gas transmits pressure evenly, allowing for consistent force application. The gas inside the spring also plays a crucial role. Nitrogen is commonly used because it is non-corrosive and provides predictable performance across various temperatures.
How gas springs work
Gas springs work on a simple principle: when you apply force to the piston rod, it compresses the gas inside the cylinder. This compression stores potential energy, which is released when the force is removed. The stored energy then extends or retracts the piston rod, depending on the application. The controlled release of energy ensures smooth and precise motion. Gas springs are widely used in applications that require lifting, lowering, or supporting heavy objects, such as car tailgates and hospital beds.
Advantages of gas springs
- Smooth and controlled motion: Gas springs provide gentle and controlled movement, preventing sudden jolts.
- Variety of sizes: These springs come in various sizes and capacities. Each design is meant for different applications.
- Maintenance-free: Once installed, gas springs require minimal maintenance.
- Safety: Gas springs enhance safety by preventing objects from falling or slamming shut.
- Durable: They have a long service life and can withstand harsh conditions.
Common applications of gas springs
Gas springs are used in a multitude of applications, such as:
-
- Automotive industry: Gas springs are used for lifting trunk lids, hoods, and tailgates, providing easy access and enhanced safety.
- Furniture: Gas springs are essential in office chairs, enabling adjustable height and comfortable seating.
- Aerospace: They are used in aircraft cabin doors and baggage compartments for smooth and controlled motion.
- Medical equipment: Hospital beds, examination tables, and rehabilitation devices rely on gas springs for precise adjustments.
- Industrial machinery: Gas springs assist in the controlled movement of heavy machinery, reducing the risk of accidents.
- Marine industry: Boat hatches and storage compartments are often equipped with gas springs for ease of use.
- Agriculture: Tractor hoods and equipment access panels are equipped with gas springs for convenient operation.
- And much more!
