Clock Spring Manufacturers

With decades of experience in precise spring engineering and production, we are trusted UK clock spring manufacturers that cater to a wide range of industrial sectors. As part of the internationally recognised Lesjöfors Group, we offer both standard and custom clock spring solutions, using ISO 9001-certified processes and innovative manufacturing technologies.

Custom Clock Springs & Reliable Stock Options

We manufacture clock springs (also referred to as a flat torsion spring) in a variety of sizes and configurations for everything from compact electronics to industrial machinery. Clock springs are a form of torsion spring, as they rotate in circular movements. Whilst torsion springs are prepared from round wires, clock springs are made from flat wires. Clock springs revolve around an object’s axis, pushing its force onto another object via the outer edge of the spring.

Our standard and custom clock springs are ideal for

  • Maintaining rotational energy
  • Returning components to a set position
  • Keeping consistent torque across a range of motion

 

Need Bespoke Clock Spring Design?

For specialised or unique applications, we offer fully custom spring design and manufacturing services. Our engineers work closely with you from initial consultation to final production to ensure every spring performs exactly as you need.

We can manufacture clock springs in various materials, including:

  • Stainless Steel (EN 10270-3-1.4310): Highly resistant to fatigue and corrosion. Ideal for high-cycle environments such as medical devices, electronics, and timekeeping components.
  • Custom Materials: For specialist applications, we can manufacture clock springs using carbon steel or other alloys as required by the application. View our full range of spring materials to see our options in detail.

There are several design considerations to factor in when placing a custom order, including torque requirements, spring dimensions (inner & outer diameters), wire width and thickness, number of coils, and mounting configuration.

Trusted Clock Spring Suppliers

As one of the UK’s most experienced clock spring manufacturers, we serve customers across the electronics, medical, automotive, aerospace, and industrial machinery sectors. Using state-of-the-art CNC winding and forming machines, we manufacture each spring to be durable, have minimal friction, and hold precise torque.


Whether you’re in need of a single prototype or a bulk production order, we provide the same level of attention to detail and performance across every project. From concept to completion, our team makes sure that your clock springs meet your specifications and perform consistently over time.

Frequently asked questions

What Are Clock Springs?

A clock spring is a type of torsion spring made from flat wire that stores and releases rotational energy in a circular motion. They are often coiled around a shaft, giving torque when rotated, and returning components to their original position or maintaining a set angular force.

Clock springs function by winding in a circular motion and applying force from their outer edge. As the spring unwinds or tightens, it applies rotational energy back to the system, which is ideal for maintaining torque across rotational axes. This is especially useful in applications were precise, controlled motion is required.

Clock springs are a versatile product that are used across a number of industries, here are just a few examples:

  • Automation: These springs can be found in automated mechanisms that require controlled and repetitive rotational motion, like robotic systems or automated assembly lines.
  • Automotive: Clock springs are found in safety systems like airbag and seatbelt mechanisms. They also are used in steering systems, enabling electrical connectivity for wheel-mounted controls.
  • Medical Devices: Where precise, controlled movements are required, clock springs are frequently used, such as in surgical instruments or within the mechanics of certain diagnostic equipment.
  • Aerospace: Clock springs are used in many areas of the control mechanism for commercial and military aircraft.
  • Everyday Items: Clock springs have a variety of everyday applications, including in wind-up toys, retractable furniture, exercise machines and bicycles. As the name suggests, they are also found in mechanical clocks and watches.

Yes. We offer fully bespoke clock spring design services. You can customise aspects such as material, torque angle, number of coils, shaft radius, and mounting configuration. Our team will assist with design, prototyping, and full production.
