Products show

Torsion springs are a kind of wire springs that operate a   rotary force. The ends of a torsion spring are attached to other mechanical parts, and when those  mechanical parts rotate around the  torsion spring, the spring tries to push them back to their original position. Not like the name implies , torsion springs are subjected to bending stress rather than torsional stress. They can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the body centerline axis.
