Designed to provide torsion, clock springs are sometimes needed in place of traditional torsion springs as they rotate in circular movements. As a kind of torsion spring, clock springs are prepared from flat wires instead of round wires. The main difference between the two lies in the way the force is presented, as a clock spring revolves around an object's axis, pushing its force onto another object via the outer edge of the spring.
We design and manufacture clock springs that are coil friction free, due to correctly mounted open style coils. However, torque capacity is reduced in clock springs, hence if you're guessing where the name comes from, one of the most common uses for clock springs is to make up stainless steel components in watches. Stainless steel is the (chosen) preferred material for clock spring technology here at European Springs because the rate of fatigue on the metal is lower, however as with our other spring products we can and do offer bespoke solutions in other spring materials.
