Global Seals offers a selection of torsion springs with legs of equal length oriented at varying unloaded angles. Torsion springs can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the body centerline axis. They offer resistance to twist or rotationally applied force.
A spring of this type will reduce in body diameter and increase slightly in body length when deflected in the preferred direction of the fabricated wind. Depending on the application, torsion springs can be designed to work in a clockwise or counter-clockwise rotation, thus determining the direction of the wind. Common torsion springs are those used in a clothes pin or a garage door.
The highest grades of spring wire are used when fabricating our torsion springs. To create cost-effective warehousing of our stock spring inventory for our customers, we offer material certification for custom springs only. Certifications of conformance for geometric tolerances set by the Spring Manufacturers Institute (SMI) are available for stock torsion springs upon request.
The term “spring steel” is a stock inventory term covering music wire, hard-drawn(MB) wire and oil-tempered wire. Additionally, stock torsion spring materials may include 300 series stainless steel.
