Strip springs

Constant force springs for tension and compression force

KERN-LIEBERS China is equipped with sophisticated machinery for the production of high-end constant force springs with the characteristics of uniform force, long extension length and low working friction.

• Spring width: 1.8 - 100 mm
• Spring thickness: 0.05 - 1.0 mm
• Material: Textured carbon and stainless steels
• Service life: Up to 50,000 load cycles (typical applications require 5,000 - 20,000 cycles)
• Minimum hysteresis.

Constant force springs as a torque generator

Constant force springs installed in biaxial mechanisms designed by KERN-LIEBERS are usually used to generate constant torque in various retractor applications.

• Spring width: 1.8 - 50 mm
• Spring thickness: 0.05 - 1-0 mm
• Material: Textured carbon and stainless steels
• Service life: Up to 50,000 load cycles (typical applications require 5,000 - 15,000 cycles)
• Up to 100 working rotations
• Small to medium torque range, minimum hysteresis, biaxial system with work roll and storage roll
