Tension springs: Full tension for every requirement
Tension springs are elastic machine elements that store mechanical energy and are stretched by an axial tensile force. When they are released, they return to their original length. They are typically made of spring steel wire and are fitted with eyelets or hooks at the ends to attach them. We develop and manufacture tension springs that meet your exact requirements - from batch size 1 to large series, transforming your products into smart components, assemblies and devices.
