Mechanical vibration will cause equipment noise, precision attenuation and structural fatigue. Silicon nitride ball bearings have excellent vibration reduction performance, which can effectively suppress mechanical vibration and improve equipment operation stability.
High spherical precision reduces rolling vibration. The sphericity error of high-quality silicon nitride balls is less than 0.1μm. The contact between the ball and raceway is uniform without jitter vibration caused by uneven stress.
Damping performance absorbs vibration energy. Ceramic material has better damping capacity than metal. It can absorb high-frequency vibration generated by high-speed operation and reduce vibration amplitude.
Low friction reduces vibration excitation source. Smooth surface minimizes friction fluctuation. No sudden friction resistance change causes periodic vibration, making the operation more stable.
Temperature stability avoids thermal vibration. Metal bearings expand with heat to produce clearance vibration. Silicon nitride has low thermal expansion, keeping stable bearing clearance and avoiding thermal vibration.
Vibration reduction bearings are widely used in precision machine tools and testing instruments. Silicon nitride balls become the key material to realize low-vibration and low-noise operation of equipment.
