Simplify complexity with the ALLIANCE® ball bearing

True to form, HL Technology innovates. In the field of watchmaking, we revolutionised the sector by introducing our ball bearing, which has two rings instead of three. Thanks to this unique technology, ALLIANCE® ball bearings are:
  • Simpler
  • More robust
  • More elegant
  • More innovative
This technological evolution offers many advantages:
  • The one-piece core eliminates the problems associated with a driven (or welded) assembly.
  • No manual adjustment affects the accuracy of the bearing; the ring and core depend on machining and accuracy. Overall process capability is greatly improved.
  • In the ALLIANCE® bearing, the balls prevent disassembly, ensuring robustness.
  • ALLIANCE® design increases ball diameter, bearing load capacity and increases bearing life.
Avec ALLIANCE®, HL Technology propose des solutions innovantes dans le domaine de l’horlogerie suisse / With ALLIANCE®, HL Technology offers innovative solutions in the field of Swiss watchmaking.
We apply this customised technology to create the bearings you need.
  • Complete solutions, from design to delivery of ALLIANCE® decorated bearings.
  • Basic and multiple decoration
  • Advanced technology (ceramic ball)
  • Decoration before assembly. No force (driving) or thermal stress (welding): guaranteed finish.
  • Choice of colours and materials of the balls (steel, ceramic, ruby, etc.)
