tension Springs are defined as a type of spring designed to support tensile or pulling loads. tension springs are usually close wound and will possess initial spring energy. Typically tension springs have hooks or loops on the ends for securing or fastening to door or other objects.
Most tension springs are wound with initial tension. This is an internal force that holds the tension spring's coils together. The measure of the initial tension is the load necessary to overcome the internal force and begin coil separation. Unlike a compression spring that has zero load at zero deflection, an tension spring can have a reload at zero deflection . This built-in load, called initial tension, can be varied within limits, decreasing as the spring index increases.
Our extension springs are available with different end configurations to facilitate the attachment to components being acted upon. End configurations that we offer include full loop,machine hook,coned end with swivel hook or bolt,crossover hook and custom shaped hook.
Applications for extension springs include automotive interiors and exteriors, garage door assemblies, appliances,furniture,engineer machines,washing devices, motor,lawnmower,garden machine,farm machinery as well as thousands of other uses. XULONG’s extension springs come in a wide array of sizes, from small medical devices to off-road machinery brake springs and marine container.
