A gas spring is a mechanical component that operates using compressed gas—usually nitrogen—sealed inside a cylinder. Unlike traditional metal springs that rely on physical deformation, gas springs use pressure and a sliding piston to generate smooth, controlled motion and absorb force along the piston axis.

At India Auto Springs Private Limited, we exclusively use high-purity nitrogen gas in our gas struts. Nitrogen is stable, inert, and non-flammable, making it ideal for consistent performance across various environments.

While the lifespan depends on usage, application type, and environmental conditions, our gas struts are engineered to last for several years under normal use—often around 4 to 5 years or more. With proper installation and no side loading, they deliver consistent performance for tens of thousands of cycles.

To determine the correct gas strut, calculate approximately 60% of your door or panel's height for the extended length. For example, a 1000 mm high panel should use a strut with around 600 mm extended length. Contact our team for exact force and mounting recommendations based on your specific setup.

The internal pressure of a gas spring depends on its model and the extension force required. Some springs can have pressures up to 150 bar or more.

Yes, in many cases the extension speed can be pre-configured during manufacturing by modifying the internal design. Custom speeds can be achieved based on your application needs.

Absolutely. We can include protective elements such as plastic end caps, bellows, or protective sleeves to shield the spring’s piston and seal from dust, moisture, and debris.

The weight of a gas spring depends on its size and diameter. On average, a gas spring may weigh anywhere from 50 grams to 2000 grams.

Each gas spring we produce comes labeled with essential details including the RPR product number (or customer-specific code on request), safety information, and manufacturing date for easy identification and traceability.

Standard gas springs are finished in neutral black powder coating. However, we also offer customized color options—such as white or grey—on bulk orders or special requests.

While temperature changes can affect gas pressure slightly, our gas springs are designed to perform reliably across a wide temperature range. Specialized models with enhanced compensation features are available for extreme environments.

Standard tolerances for our gas springs are ±3.0 mm for total extended length and ±2.0 mm for stroke length, depending on the product variant.

Some gas springs may produce minor operational sounds due to the internal flow of gas or oil, especially in models with speed control features. These sounds are normal and typically application-dependent.

Our support team is always available to assist. For specific queries, you can contact our market segment experts listed on our website, or reach out directly to our sales and engineering teams.

Standard brochure or catalog models are usually dispatched within one week after order confirmation. Please note that the catalog includes only a portion of our full product range.

Yes. We offer gas springs in a variety of sizes, lengths, and force outputs. Intermediate or customized specifications can be developed to suit unique applications.

Depending on the design, our gas springs are available from as low as 5 kgf (50N) up to over 200 kgf (2000N), accommodating a wide spectrum of load-bearing requirements.

We provide a broad range of end fittings including plastic or metal options—such as ball joints, clevises, brackets, or threaded ends—to suit diverse mounting needs.

No, our gas springs are completely maintenance-free. They are sealed and pre-lubricated for life, requiring no additional servicing during their operational lifespan.
