Tension springs
Tension springs, also known as extension springs, are typically cylindrically wound coiled bodies of round wire, with both ends featuring eyelets or hook shapes. These springs are designed to absorb and store energy through their helical winding, which is mainly subjected to torsion.
Velleuer is a leading extension spring manufacturer and supplier, producing high-quality helical tension springs made from patented, drawn spring wire and stainless steel. These springs are suitable for static, quasi-static, and dynamic loads, with added assurance of a 100% inline test for force and geometry to ensure optimal performance.
Our comprehensive manufacturing capabilities include all common spring production processes, along with cleaning and surface coating options, making Velleuer the trusted choice for custom tension springs and extension springs.
Contact Velleuer today to discover how our precision tension springs and extension springs can meet your exact requirements.
The winding body and eyelet or hook shape of a helical tension spring depend on, and can be customised in line with, its function and the available installation space.
