Constant Force Spring

Constant force springs are a type of spring that exert a constant force throughout their deflection. They are commonly used in various applications where a constant force is required, such as in retractable cords, counterbalances, and tensioning devices.

In the supply class Coil, Flat, Leaf, and Wire Springs, constant force springs are available in different forms:

1. Coil Springs: These constant force springs are made from a tightly wound coil of spring steel. They provide a consistent force over a wide range of deflection.

2. Flat Springs: Also known as clock springs, these constant force springs are made from a flat strip of spring steel wound in a spiral shape. They are commonly used in applications where space is limited.

3. Leaf Springs: These constant force springs are made from a series of flat spring steel strips stacked together. They provide a linear force output and are often used in automotive suspensions and industrial machinery.

4. Wire Springs: These constant force springs are made from a single piece of wire formed into a helical shape. They are versatile and can be used in various applications, including automotive, aerospace, and medical devices.

These constant force springs can be found in the supply group Hardware and Abrasives, which typically includes a wide range of hardware components and abrasive materials used in various industries.

When selecting a constant force spring, it is important to consider factors such as the required force, deflection range, space limitations, and environmental conditions. It is recommended to consult with a supplier or engineer to ensure the appropriate constant force spring is chosen for your specific application.
