Clock springs, also known as
power springs, are the oldest form of flat spring and the most common type in use today.
Clock springs are produced by tightly winding tempered spring material on an arbor and attaching the free end to a metal or plastic case.
The spring’s natural tendency to expand imparts a moment to either the arbor or case, producing usable torque. The torque generated is cumulative so that the force increases as the spring is wound tighter and decreases as it unwinds.
Clock springs can be shipped in customer-designed retainers for direct insertion into the customer’s product or simple retraining rings for transfer to the customer’s housing.
