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
