Spiral Springs

Spiral springs are flat strip springs wound into a spiral to store rotational energy.

Spiral Springs

Spiral springs (also known as clock springs or power springs) are flat strip springs wound into a spiral to store rotational energy.

When deflected, the spring delivers torque rather than linear force, making them ideal for applications requiring controlled rotation or energy storage over multiple turns.

Spiral springs are commonly used in retracting mechanisms, counterbalance systems, cable reels, seatbelt systems, and timing devices.

Spiral Spring Parameters

The following parameters are important in establishing the correct design of spiral springs:

  • The required torque and number of turns
  • The inner and outer diameter constraints
  • The direction of wind and method of attachment
  • The strip thickness and material selection
  • The operating speed and cycle life
  • The operating environment, which will determine the choice of material and any protective finish
