Double torsion spring

Double torsion springs are used in mechanical systems where controlled movement, rebound and balance are required. In contrast to single torsion springs, they offer two-way resilience, making them ideal for applications with rotating or symmetrical loads. At De Spiraal, we design and produce fully customized double torsion springs, tailored to your technical specifications, load requirements and installation situation. Whether it's mechanical engineering, medical or lighting applications, we provide springs that perform with precision.

What is a double torsion spring?

They are commonly used in mechanical systems that require controlled return movement, dual-sided tension, or self-closing functions, ranging from valves and lids to control mechanisms and precision equipment.

  • Mechanical engineering: Spring-loaded shafts, valve systems with dual opening directions, and return mechanisms.
  • Medical: Surgical equipment, dosing mechanisms, and systems requiring precise rotational loads.
  • Defence & Aerospace: suspension systems for armoured vehicles, automatic weapon systems, and moving components in vehicles and equipment.
  • Lighting technology: Durable and stable solutions for systems with adjustable or rotational components on both sides.

Double torsion springs combine strength, precision, and symmetry in a single compact spring solution. By incorporating two active torsion zones, they deliver increased torque in both directions, making them especially suitable for double-acting applications. The symmetrical operation ensures balanced force distribution, which is essential in systems where equilibrium is critical.

Thanks to their efficient design, double torsion springs provide high performance even in applications with limited installation space. In addition, these springs are fully customisable: from wire diameter, number of coils, and winding direction to leg shape and material selection. The spring rate, which determines how linearly the spring responds to angular deflection, can also be precisely matched to your application.

  • Custom manufacturing: Designed specifically for your application, from single prototypes to series production.
  • High-quality materials: Stainless steel, spring steel, or special alloys, selected to match environmental and load requirements.
  • Technical expertise: Support from concept to final product, including calculation and prototyping.
  • Fast delivery: Enabled by modern production methods and efficient processes.
  • Reliable performance: Precise torsional action, high fatigue resistance, and long service life.
