What Are Torsion Springs?
Torsion springs are helically wound springs that exert torque when twisted. They store and release rotational energy, typically around a shaft or axis. Springtech manufactures custom torsion springs that deliver precise torque control for high-cycle and safety-critical systems.
These springs are used to open, close, balance, or return mechanisms across industries such as aerospace & defence, industrial and medical. Our engineers help you select the right coil direction, leg position, and torque range to match your exact operating parameters.
