The classic power spring retains its importance to this day. Power springs are used where space constraints and the size of the spring do not allow the use of Maximo springs, or where they are required by specific customer applications. These springs are wound by machines developed and built by KERN-LIEBERS. Spring width: 1.8 – 100 mm Spring thickness: 0.05 – 3.0 mm Material: Martensitic spring strip steels, textured carbon and stainless steels Service life: Very long, depending on the design Up to 30 working rotations Typical applications of power springs include: Cable and hose retractors Fall protection devices Balancers Actuators Starter springs in small clockwork motors Timepieces Overhead line systems
