Locking mechanism for cabriolets

Application for the automotive industry pdf_blue_large

Locking mechanism for cabriolets



  • The existing product, consisting of standard bearings, had problems with overload and corrosion.
  • The cost price was high due to the number of components coming from different sources.



  • JESA’s experience in ball bearing technology,
  • judicious choice of materials and
  • optimization of lubrication and geometry

represent indisputable progress.



  • JESA designed a full complement bearing with 4 points of contact combining an insoluble lubricant and stainless steel components.
  • The JESA solution integrates a ball race directly in the threaded shaft itself and a nut made from injected plastic, containing a lubricating additive, PTFE.


Customer benefits

  • A new, optimized and reliable mechanism allowing increased axial loads, reduced friction and a threefold increase in lifetime compared to the original arrangement.
  • The customer has a mechanism from a single supplier, enabling it to reduce its internal logistics and its costs
