Precision-grade bearings with the longest life

All our bearings (and the contact areas of their rings) are repeatedly exposed to stress exceeding 1,000 MPa as part of our rigorous testing.

We consider our material types, purity, and hardness to be important – because we aim to provide you with the longest bearing life, even under high loads.

How our bearings solved a problem - and broke a record

When Swiss watch manufacturers were looking to create the axles of their renowned Tourbillon watches, they came to us. Long considered one of the most difficult watch parts to produce, the construction traditionally requires extremely strong, precise jewels such as Ruby.

We were able to work to develop a miniature ball bearing with an outer diameter of just 1.4978mm: small and perfect enough to be used instead of a jewel.

Apart from setting a new standard in watchmaking, we were awarded the Guinness World Record for the smallest commercially-available ball bearing.
