Grade 5 Tungsten Carbide Bearing Balls
Grade 5 tungsten carbide bearing balls are ultra-hard precision components used in roller bearings for wafer slicing saws in semiconductor manufacturing. Their extreme hardness provides durability against abrasive materials like silicon boules, making them essential for precise cutting operations. They are classified under this tariff item as 'other' balls for ball or roller bearings.
