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.
Hybrid ball bearings are the future for electric motor manufacturers. The demand for stronger and more durable bearings for electric motors is increasing and in many applications, conventional steel balls in motor bearings are no longer sufficient.
The requirements for bearings for an electric motor are numerous. They must bear the load of the shaft and be precise in order to keep the distance between the rotor and stator small and constant. In addition, a motor with variable speed control via pulse width modulation (PWM) must be able to cope with different speeds. At the same time, the bearings should operate quietly and vibration-free.
The CeramicSpeed Insulate product line addresses all of these points to offer you the best solution package in a bearing. Our highest quality ceramic silicon nitride (Si3N4) balls offer a four times smoother and two times harder surface compared to steel balls. This results in a much lower internal bearing rolling resistance, which saves energy. The bearing operating temperature is reduced by up to 40°C and vibrations in the bearing are reduced. As the ceramic material is lighter compared to steel, it offers higher speeds under the same operating conditions as the steel bearing of the same size.
