Product Announcement from Century Spring Corp.

Torsion Springs-Image

Torsion springs are commonly referred to as hinge springs or 'mouse-trap' springs. They are used for storing and releasing angular energy or for the purpose of statically holding a mechanism in place by deflecting the legs about the body centerline axis. The torsional body will reduce in body diameter and increase in body length when deflected in the preferred direction of the fabricated wind.
