Extension Springs
Extension springs, also known as tension springs, apply a resistive force as the spring extends and are commonly utilised to move or return a component part. Extension springs require special ends to permit application of the load and these ends assume many forms.
Product Details
Extension springs absorb and store energy as well as create a resistance to a pulling force. Extension Springs are attached at both ends to other components. When these components move apart, the extension spring will pull components together again.
Key specifications include the spring rate, helix type, spring ends type, wire diameter, material, and free and maximum extended lengths. Extension springs are used primarily in manufacturing applications where a variable, opposing force is required between two components. There are many sizes, spring rates, and materials available depending on the holding forces required. The ends are usually formed in the shape of a hook or loop and can also be custom made. Different types of spring ends are used with extension springs, and many of these are standardized for specific applications, usually formed in the shape of a hook or loop, and can also be custom made. You can learn more about these spring end options in our related guide on the extension spring end types.
Extension springs are normally fashioned from wire and are not self-limiting: they can be stretched beyond their limits and are thus are limited to applications where failure isn’t a critical issue. Extension springs are often wound to order but are available in stock sizes and also as assortment kits.
