SINC CERAMIC
Techno­logy

At DT Swiss we believe that the difference is in the detail. SINC ceramic ball bearings are precisely based on such details. Thanks to the optimization of these details, a DT Swiss wheel with a SINC upgrade simply means that you will be ahead of the field, your friends or setting new personal bests.

choose nothing else but SINC ceramic bearings for their race bikes. Comes raceday, it gives them one more advantage to know and actually have the very best in bearing technology.

SINC ceramic ball bearings have been developed by DT Swiss as a system. They are based on balls made from silicon nitride (Si3N4), an extremely tough and wear- and corrosion-resistant ceramic material. The bearing rings are made from a specially developed steel alloy, which is adapted to the properties of the specific ceramic material used and are precision ground. This combination reduces the rolling resistance to an absolute minimum and guarantees greater durability than conventional ball bearings.
But it is not just the bearing itself that is conceived as a system. It's only by using tolerances within a few thousandths of a millimeter and precisely tuning the tolerances of DT Swiss hub bearing seats that SINC ceramic bearings deliver their full potential and offer the decisive advantage over competing products.

Advantages of DT Swiss hubs with SINC ceramic

Even when installed, the optimum distance between the ceramic balls and the bearing ring (clearance) is ensured. This guarantees minimum rolling resistance and prevents bearing wear

The combination of ceramic bearings and steel bearing rings (hybrid bearings) mean that corrosion between balls and ring is impossible, which significantly improves the lifespan. The bearing ring is also permanently smoothened by the extremely hard balls, which ensures a permanently minimal rolling resistance.

The bearing cage, which holds the balls in position, consists of a material ideally suited to the material of the ceramic balls and is specifically developed for each bearing size. This means that the balls and cage fit together perfectly, which further minimizes friction in the bearing.

The high-quality SINC ceramic bearing sealing system guarantees perfect functioning and minimum friction in all conditions. Here is how: A sealing ring is only used on the outside; only a protective ring is used on the inside. The seal seat is precision ground for perfect seal concentricity, which ensures minimum rolling resistance. This technology is unique and is only used for SINC ceramic bearings

Every DT Swiss SINC bearing is individually inspected and tested.
