GAS SPRING / TAIL GATE LIFTER ASSEMBLIES (4 WHEELER)
A gas spring is a sealed mechanical device that uses compressed gas to generate a controlled outward force, providing smooth lifting and support for lids, panels, and movable components. In automotive applications, gas springs are essential for assisting the opening and holding of car bonnets, dicky lids, tailgates, and other access panels, ensuring controlled motion, enhancing convenience, and preventing sudden closures that could cause injury or damage.
Harisons gas springs stand out for their exceptional reliability and manufacturing quality, with robust materials and precision engineering that deliver long-lasting performance even under frequent use. Our thoughtful design ensures balanced force and smooth motion.
Key Features and Specifications
Features: Gas Springs/ Gas struts are sealed, pneumatic lift and support devices that use compressed gas to provide smooth, controlled motion for lifting, lowering, and positioning, ideal for doors, lids, hatches, furniture, and machinery.
- High-Pressure Nitrogen Filled: Each gas spring is charged with high-pressure nitrogen gas, which creates a stable and consistent extension force throughout its stroke, providing predictable motion control.
- Durable Piston Rod & Seal Design: A well-engineered piston rod paired with robust seals ensures the internal gas stays contained while the rod slides smoothly, contributing to longer service life and reduced leakage.
- Corrosion Resistance: Gas springs are built with materials and surface treatments that resist rust and degradation, helping them perform reliably in environments prone to moisture or wear.
- Low Maintenance: These units are self-contained and sealed, so they do not require external adjustments or frequent servicing, saving time and upkeep cost over their lifetime.
- Smooth Damping: Integrated internal damping, with controlled gas and oil flow, gentle and controlled motions, reducing impact noise and stress on connected components.
- Safety & Load-Holding Capacity: Designed to support and hold a specified load safely, gas springs prevent sudden slamming or collapse of panels, providing reliable load-bearing performance in demanding applications.
Specifications: Our gas springs are defined by several precise technical specifications that ensure they perform reliably in automotive and industrial settings.
Specifications | Details |
Force | Measured in Newtons (N), indicates support/lift capacity. Typical range: ~50 N to 3000 N or more. |
Stroke Length | Distance piston rod travels between compressed and extended positions; e.g., 30 mm – 600 mm+. |
Extended and Compressed Length | It varies based on model and stroke. |
Cylinder and Rod Diameter | Cylinder diameters are often 15 – 40 mm, rod 6 – 20 mm for standard gas springs. |
Material | Typically steel tube with a treated steel rod for strength and corrosion resistance. |
Operating Temperature Range | Most standard gas springs perform reliably from about –30 °C to +80 °C. |
Life Cycle | Rated life can range depending on design and use. |
Mounting Type | Common fittings include ball joints, eye ends, fork ends, brackets, chosen based on mounting points and motion needs. |
How It Works?
Gas springs use compressed gas and a piston system to create smooth, controlled motion, providing lift support, damping, and motion control for many industrial and consumer applications. Inside a gas spring is a sealed cylinder filled with high-pressure nitrogen gas and a piston attached to a rod. When an external force pushes the rod into the cylinder, the gas inside is compressed, storing energy and increasing internal pressure.
Hence, this compressed gas then pushes the piston back outward, creating a controlled extension force. The internal gas pressure generates the force needed to help lift heavy components and hold them steady, while precision seals and the piston design regulate how smoothly the motion occurs and prevent sudden movement.
Applications of Gas Spring
Gas springs are widely used throughout a vehicle to move heavy or frequently accessed parts more easily, safely, and more controlled.
- Car Bonnet/ Hood Support: Gas struts are widely used to assist lifting and holding the car’s bonnet or hood. Instead of a manual prop rod, gas springs enable the bonnet to open effortlessly and stay securely in place while accessing the engine bay for maintenance or inspection.
- Passenger Seat Support & Adjustment: Gas springs are also applied within seat mechanisms to assist with height and recline adjustments, offering smooth, ergonomic movement for better comfort and posture.
- Trunk or Dickey Lid: In both sedans and hatchbacks, gas springs support the trunk (boot) lid, providing a controlled opening and closing action. They hold the lid open safely so you can load or unload luggage with ease.
Tailgate / Hatchback Lift Assist: For SUVs, hatchbacks, and station wagons, gas springs are used on the rear tailgate or liftgate. They ensure smooth lifting and secure holding at any height, improving accessibility to the cargo area and enhancing user comfort.
Benefits of Gas Spring
Gas springs offer several practical benefits that make them ideal for automotive and other applications.
- Reduces manual effort/ improves safety: Gas springs make lifting and holding heavy parts easier and safer by providing reliable support and preventing sudden drops.
- Smooth Opening and Closing: Deliver controlled, dampened motion, ensuring smooth movement without jerks or slams.
- Longer Service Life, Maintenance Free: Sealed gas springs require no regular servicing and are built to last through many cycles.
- Compact Design, Saving Space: Their space-efficient construction allows installation even in tight areas.
- Reliability Under Varying Temperature Conditions: Designed to perform consistently across a range of operating conditions.
- Quality Assurance: Manufactured and tested under strict quality controls to ensure dependable performance.
