Ceramic ball bearing for power transmission organs


The movement manufacturer is often faced with the problem of designing a wheel train or driving wheels in a confined space.

The compact dimensions of the smallest Mobix [D 1.28 mm x H 0.50 mm] and the extensively-proven efficiency of ceramic ball bearing technology offer new opportunities for the designers of timekeepers.

A team listening to your concerns

The constraints when constructing an ultra-thin mechanical watch drive movement designers to seek solutions that limit the thickness of components as much as possible.

To meet this need, our engineers have developed the Mobix line to drive wheel trains or gears as suspended over the plate, thus achieving a significant height reduction compared with the traditional construction of a wheel mounted between plate and bridge.
