NBK’s Flexus^® are multi-functional parts made of various materials with machined slits; the portion between the slits works as a spring by applying coupling’s techniques and expertise, therefore one can achieve their targeted spring constants.
  The Flexus^® enable various spring properties such as compressing, tensioning, shearing, and bending.
Due to the cutting process, exact spring constants can be obtained for use in instruments where precision and reliability are required that coiled springs cannot achieve.
  The shapes and dimensions are flexible. Polygonal shapes as well as cylinders can be manufactured.
  Flexus^® can be designed with many materials such as aluminum alloys, stainless steels, engineering plastics, copper alloys, and more thereby matching customer’s needs.
