Helical tension springs are usually cylindrically wound bodies of round wire, both ends of which have an eyelet or hook shape. The wound body of the helical tension spring is mainly subject to torsion. Helical tension springs are standardised.
Lesjöfors Springs Slovakia s.r.o. produces only helical tension springs made of cold formed spring wire and stainless steel for static, quasi static and dynamic loads.
The wound body and eyelet or hook shape of a helical tension spring depend on its function and the available installation space.
