Locking mechanism for cabriolets

Background

• 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.

Innovation

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

represent indisputable progress.

Solution

• 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
