The special feature of the Maximo power spring is that the combination of winding forward and then back increases the power density, making maximum use of the available material properties. The machinery and equipment required for this special process is developed and built internally at KERN-LIEBERS.
Spring width: 1.8 – 100 mm
Spring thickness: 0.05 – 0.55 mm
Material: Textured carbon and stainless steels
Service life: Up to 500,000 load cycles
(typical applications require 100,000 – 200,000 cycles)
Up to 50 working rotations
Flat characteristic curve in the work area, low hysteresis
The material volume is fully exploited at maximum torque
Characteristic S-shape in unwound exposed position
Typical applications of Maximo springs include:
Seat belts
Dog leashes
Cable retractors
Roller blind drives of all types
Measuring tapes
