Constant Torque Springs
The spring in its natural state is wound back to the output wheel using an external force. When the external force disappears, the spring is wound back to its natural state and at the same time the torque is generated without any change in torque due to an increase in the number of revolutions. Constant torque springs are suitable for use with products designed for a large number of revolutions.
To satisfy the requirements of these different applications, Jau Liang Ji Co. offers customized constant torque springs for applications and solutions based on years of expertise and experience, with sizes to suit your needs. Our experienced engineers can assist you with your spring design, please contact us for more information.
