What is a metal tension spring?
A metal tension spring is a helical spring designed to absorb tensile forces and store mechanical energy when stretched. As soon as the tension is released, the spring returns to its original shape, creating a controlled retraction force. This makes tension springs essential in applications where tension needs to be regulated or where components need to be automatically brought back into position.
De Spiraal produces metal tension springs in various dimensions, strengths, and materials, tailored to your specific application. The ends can be provided with hooks, eyes or threaded connections, so they can easily be attached to other parts. Thanks to the shape, diameter, wire thickness and pitch, the strength and spring characteristics are determined.
Why choose metal tension springs?
Metal tension springs are used to be stretched repeatedly without deformation, while maintaining their performance for a long time. Because they offer an ideal combination of strength, flexibility and durability, they are perfect for applications in many sectors such as mechanical engineering, medical, aviation & defense and agriculture.
To ensure that De Spiral produces high-quality extension springs, we offer a wide range of materials, such as spring steel (hardened steel), stainless steel (stainless steel 302, stainless steel 316), phosphor bronze. If necessary, we will help you choose the right material for your specific application. Thanks to our experience, we can advise you on customized solutions and fast deliveries from stock, so that your project can be realized quickly and efficiently.
Applications of metal tension springs
- Mechanical engineering: In mechanical engineering, metal extension springs are often used in applications where controlled force and energy storage are required. They are applied in automated systems, conveyor belts, fans, and as part of damping mechanisms in machines and equipment. Thanks to their flexibility and durability, they contribute to efficient operation and a long service life of machinery.
- Agricultural sector: In the agricultural sector, metal extension springs are widely used in machines such as combine harvesters, seed drills, and irrigation systems. They contribute to the suspension and damping of moving parts, ensure precision in mechanical operations, and enhance the stability of agricultural equipment. This is particularly important in rough environments, where our extension springs provide reliable performance.
- Medical sector: In the medical sector, metal extension springs are used in equipment such as infusion pumps, surgical instruments, and respiratory devices. Thanks to their precision and reliability, they ensure the correct force and movement in medical applications where every millimetre and effort is essential for the safety and effectiveness of the medical device.
- Defence & Aerospace: In the defence and aerospace sectors, metal extension springs are used in a wide range of applications, from landing gear and cockpit mechanisms to weapon systems and radar installations. These extension springs provide the required force, reliability, and resistance to extreme conditions such as high speeds, temperature fluctuations, and heavy loads.
Benefits of our metal extension springs
Thanks to our experience, we can fully tailor tension springs to the specific needs of your application, so that you always get the right solution for your project. Whether it's load capacity, precision or reliability, our tension springs provide consistent performance, even under heavy loads. Most common finishes are German eyes, English eyes, double eyes or spring plugs that can be adjusted to the desired connection or attachment. This flexibility makes it possible to easily integrate the tension springs into different systems so that they function optimally regardless of the complexity of the application. Choosing the right end ensures efficient operation and reliable performance, even under the most demanding conditions.
