Traction spring Maximo series

coiledflatconstant-force

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
