Spiral torsion springs, also referred to as clock springs or flat spiral springs, are precision-engineered components commonly manufactured from high-carbon steel or stainless steel. These springs are wound in a flat state and are uniquely designed so that their coils remain separated and do not come into contact with each other during operation. One end of the spring is securely fixed in place, while the other is attached to a rotating component, allowing the spring to generate controlled torque. This specialized design not only provides a more consistent and reduced force output but also eliminates coil friction entirely when properly installed. As a result, spiral torsion springs offer smooth, reliable performance in a wide range of mechanical applications, making them ideal for use in various industries, including automotive, aerospace, medical devices, and industrial machinery.

Spiral torsion springs are one of the most commonly utilized types of flat springs, frequently serving as a practical alternative to traditional torsion springs. These springs function by rotating in circular motions, delivering a consistent and linear torque per revolution within the first 360 degrees of rotation. However, as the angular rotation extends beyond 360 degrees, the coils gradually tighten around the arbor, causing the torque per turn to increase significantly. This results in a nonlinear torque output, particularly as the rotation moves closer to the axis. Due to these unique mechanical properties, spiral torsion springs are ideally suited for applications that require precise torque delivery within a limited range of motion, typically less than 360 degrees of angular rotation.
Linear torque delivery within the first 360 degrees of rotation.
Nonlinear torque increase at greater angular rotations as coils tighten.
Compact design that maximizes efficiency in confined spaces.
Durable and reliable performance for a wide range of applications.
Rewind devices: Used in mechanisms that require controlled retraction, such as tape measures or hose reels.
Office equipment: Found in printers, copiers, and other devices requiring precise rotational movement.
Motors and generators: Provide torque and assist in rotational energy transfer.
Counterbalances: Help balance loads in systems like garage doors or industrial machinery.
Door closers: Ensure smooth and controlled closing of doors in residential and commercial settings.
Electrical switchgear: Used in electrical systems to manage rotational force in switches and breakers.
Home décor: Incorporated in decorative items like rotating displays or adjustable fixtures.
Retracting devices: Essential in tools and equipment that require spring-loaded retraction mechanisms.
Point-of-purchase displays: Enable rotating or moving components in retail displays to attract customer attention.
Spiral torsion springs are a versatile and efficient solution for applications requiring controlled torque and limited rotational movement, making them a popular choice across various industries.
