Constant Force Torque Springs

SPIROFLEX Constant Force Torque Motor Springs

Constant Force Torque Springs

SPIROFLEX torque motor springs are available from a standard range or bespoke design.

Constructed from a specially stressed constant force spring, SPIROFLEX torque motor springs provide high amounts of torque in a small package. These springs provide rotational energy from the torque output drum (D3), or linear motion with the use of a pulley, cable, or webbing. 

  • Spring width: 1.8 to 100 mm
  • Spring thickness: 0.05 to 1.0 mm
  • Material: Textured carbon and stainless steels
  • Service life: Up to 50,000 load cycles
    (typical applications require 5,000 – 15,000 cycles)
  • Up to 100 working rotations
  • Small to medium torque range, minimum hysteresis, biaxial system with work roll and storage roll

SR Motor Spring Range

Because there are a number of different torque spring design solutions for a given application it is suggested that if a torque spring outside our catalogue range is required that you consult with our sales department early in the design phase.

Typical applications of SPIROFLEX constant force torque springs include:

  • Power generation
  • Retracting cables
  • Drive mechanisms
  • Measurement of linear movement
  • Medical imaging equipment
