Magnetic Constant Force Springs


  • magnetic constant force springs let masses float
  • ideal construction element to compensate the weight force in vertical applications
  • constant force along the working stroke
  • strokes available from 50 mm up to 350 mm
  • constant force available from 3 N up to 60 N
  • no additional supply energy required - inherently safe
  • low moving masses
  • minimal wear
  • ideal alternative to pneumatic or spring force compensations
  • magnetic constant force springs are no dampeners


  • weight force compensation
  • constant force actuator
