Tension springs 100% Dutch Made! Tension springs have the windings pressed together. When used, the springs are pulled apart under a certain force. When this force is taken way, the spring returns to its original position. To pull the tension springs apart, they have to be equipped with eyes or spring studs. German eyes & English eyes A German eye is a reversed winding English eyes have the winding go over the heart of the spring before it forms an eye. For both types of eye a difference is made between open and closed eyes. In open eyes, the eye is hooked into something, in closed eyes something is hooked in the eye. Another option is to equip the tension spring with double eyes, or a metal stud (spring studs). It is of course possible to customise another type of eye to your specifications. Applications Some good examples of the use of tension springs: Trampolines Mechanism of garage doors Fitness equipment Doorsprings Breaking mechanism of bikes and scooters Lesser known, but indispensable for sure, are applications of the tension spring in machines in the production industry, food industry, shipping industry, aviation, agriculture, and automotive industry. There are also numerous other industries and sectors where compression springs play an important role.
