💡 Why choose Si₃N₄ ceramic hybrid bearings for high-speed applications?
Si₃N₄ ceramic balls are lighter, harder, and smoother than steel, resulting in lower friction, cooler operation, and extended service life. Combined with stainless steel rings and ABEC-7 precision, these bearings offer peak performance in high-RPM, low-noise, and demanding environments.
