Constant force springs

Because they provide a uniform force, constant force springs are used in many industries as a retraction element. They can be used as tension/compression springs for long extensions with constant force and as torque generators with controllable spring characteristics.

 

  1. Spring width: 1.8 - 100 mm
  2. Spring thickness: 0.05 - 3.0 mm
  3. Material: Textured carbon and stainless steels
  4. Service life: Up to 50,000 load cycles
  5. Minimum hysteresis
  6. Very uniform force-displacement characteristic
