Balls made of silicon nitride
Balls made of silicon nitride are characterized by excellent properties in terms of smoothness and hardness and are much lighter (58%) than steel balls due to their lower density. This means that less energy is required for the drive.
However, the low weight in particular leads to a longer bearing service life and reduces the centrifugal forces acting on the raceway. Material wear is also significantly lower, which considerably extends the service life of the bearing. Another advantage is the significantly higher permissible speed of up to 50 % and therefore the possibility of using durable bearings in demanding applications with high speeds, such as machine tool spindles or turbomachinery.
Another advantage of ceramic balls over steel balls is the significantly lower coefficient of friction, which considerably reduces the need for lubrication. Less lubrication Regular lubrication is crucial for the service life of a bearing. Direct contact between the steel ball and the steel raceway can lead to rapid bearing damage. Steel on steel has a coefficient of friction of 0.8, whereas steel on ceramic has a coefficient of only 0.2 – even less with coated raceways. The use of ceramic balls therefore solves the problem of two identical materials damaging each other. In contrast to steel bearings, the extreme hardness and surface quality of ceramic balls prevents any damage to the raceways. Thanks to these excellent properties, CeramicSpeed Ball Bearings can be used in a wide range of applications.

Motorsport
More speed thanks to more power and a longer service life The elimination of friction thanks to CeramicSpeed Ball Bearings means more speed with less effort. In addition, the lower rotational weight leads to faster acceleration and less friction, which is made possible by high-quality ceramic bearings.
