Spiral Springs

Spiral springs sometimes are called flat torsion springs, clock springs, they are made of flat stainless steel strips and be coiled through the specialized coil forming machine.

Spiral springs can store & release rotational torsion energy, they are normally mounted in a housing and fixed with an arbor in the inner coil. Torque can be generated from either the arbor or the spring housing, for this feature, spiral springs are wildly used in applications that require a high force out with limited space.

Yongsheng designs & manufactures various spiral springs like power springs, spiral torsion springs, etc.

  1. Specialize in spiral springs for nearly 20 years.
  2. One-stop shop including plastic injection housing, mounting & assembly service.
  3. Quick prototyping within 3 days.

    Spiral springs sometimes are called flat torsion springs, clock springs, they cover power springs and spiral torsion springs.

    power springs

    Spiral springs are made of flat strips, after being coiled, they can generate uncoil force. We usually mount it in a housing and fix an arbor with the inner coil, torque can be generated either the rotating the housing or the arbor.

    Bigger output with a limited room makes it wildly used in many applications like hose reels, carbon brushed, medical devices, etc.

    We usually use the prestressed steel strip to make the spiral springs. Spiral springs are divided into power springs and spiral torsion springs.

    Spiral torsion springs can be coiled through the coil forming machine.

    spiral torsion springs
    As for the power springs, after coiling through the coil forming machine, they need to recoil through the special winding machine, for the prestressed power springs, they even need to go through the rewinding process after winding.

    pre-stressed power spring

    Spiral springs can generate powerful torsion output in the limited room, this feature makes them wildly used in many applications like the hose reel, car seat belt, carbon brush, etc.

    in order to use the spiral springs, we normally need to fix the outer coil of the spiral springs into the housing and fix the inner coil of the spiral spring to the arbor.
    when rotating the housing or arbor, the counterpart rotational torque will be generated.

    Spiral springs are made of flat strips, the materials can be stainless steel, carbon steel, Inconel.

    Yongsheng normally use the 301 high yield stainless steel strip to produce spiral springs, which features anti-rust, long lifespan, well mechanical performance

    Compare to carbon steel, stainless steel have better mechanical performance and is easier to form. normally we can’t use carbon steel to make spiral springs which a width less than 0.3mm.

    Inconel is too expensive, we seldom use it except for some special application.
