đź’ˇ Why are full ceramic Si3N4 bearings ideal for extreme applications?
They’re engineered to perform where metal bearings can’t survive.
-
Silicon Nitride resists wear, heat, and corrosion
-
Perfect for non-lubricated or high-speed operation
-
Non-conductive and lightweight for sensitive equipment
-
Common in aerospace, vacuum chambers, and precision instruments
