Stainless Steel Gas Strut Specifications

Stainless Steel Gas Strut Specifications

When selecting or replacing a gas spring, it is important to measure the key dimensions accurately. Start with the Rod Diameter and Body Diameter, which determine the strength and load capacity of the gas spring. Next, measure the Stroke, which is the distance the rod can travel between the fully compressed and fully extended positions. Finally, record the Extended Length, which is the total length of the gas spring from the center of one end fitting to the other when fully extended. By following these steps, you can ensure the correct specifications for your application and achieve reliable performance.

Gas Spring End Fittings

Gas Spring End Fittings

Gas strut Ball Ends

Gas strut Ball Ends

Gas strut ball ends, also called ball joints or ball sockets, are essential fittings that connect gas springs securely to mounting points. They allow smooth pivoting movement, reduce wear, and improve load transfer. Available in steel, stainless, or plastic, ball ends ensure durability, easy installation, and reliable performance in varied applications.

Eye End Fittings

Eye End Fittings

Eye end fittings are precision-engineered connectors that attach gas springs to brackets or mounting points, providing a secure and stable connection. They allow controlled pivoting motion, reduce wear, extend the lifespan of the gas strut, and enhance operational safety. Eye end fittings are suitable for automotive, marine, industrial, and furniture applications.

Female Rod Ends

Frequently Asked Questions

Frequently Asked Questions

The service life of a gas spring depends on cycle usage, installation quality, and environmental exposure. High-quality stainless steel gas springs typically last tens of thousands of cycles when properly maintained.

In most cases, gas springs are not repairable because they are factory-sealed under high pressure. Replacing them with the correct model is the recommended and safest solution.

Choosing the right gas spring involves measuring the object’s size and weight, determining mounting positions, and calculating the required force. Gastac also provides calculation tools and custom design services to ensure accurate selection.

To measure a gas spring, you need to determine its extended length (from end to end), the compressed length, and the diameter of the rod and tube. Accurate measurements ensure proper fit and performance for your application.

To calculate the appropriate gas spring, consider the weight of the object, the distance from the pivot point, and the required opening and closing force. Using these parameters, you can select the correct force and stroke length with the help of our Gastac gas spring calculato

Gas springs should be installed with the piston rod facing downward to ensure proper lubrication. Correct alignment, secure mounting brackets, and avoiding side-loading are key for safe and long-lasting performance.

When replacing gas springs, match the size, force, and mounting type of the original part. For safety, always release the load before removal and install the new strut securely in place.
