Products classified under HTS 8482.91.00.30
Precision Chrome Steel Bearing Balls
High-precision chrome steel balls used in ball bearings for semiconductor wafer grinding machines, ensuring minimal surface deviation for accurate wafer preparation. These balls fall under HTS 8482.91.0030 as they are specifically 'other' balls for bearing parts, distinct from standard sizes. Their use in high-tech manufacturing aligns with equipment for processing semiconductor materials.
Ceramic Silicon Nitride Bearing Balls
Non-corrosive silicon nitride ceramic balls for high-speed bearings in crystal grinders and wafer polishers during semiconductor boule processing. Classified under HTS 8482.91.0030 as 'other' bearing balls due to material and precision specs beyond standard steel. Ideal for environments requiring chemical resistance in semiconductor fabrication.
Grade 5 Tungsten Carbide Bearing Balls
Ultra-hard tungsten carbide balls (Grade 5 precision) for roller bearings in wafer slicing saws, providing durability against abrasive semiconductor materials like silicon boules. HTS 8482.91.0030 covers these as 'other' balls not fitting standard categories, suited for high-wear semiconductor processing equipment.
1/8 Inch Stainless Steel Bearing Balls
Corrosion-resistant 1/8 inch 440C stainless steel balls for bearings in float zone crystal pullers, maintaining purity in semiconductor boule growth. Under HTS 8482.91.0030 as 'other' due to size and application in specialized machinery.
3mm Grade 10 Zirconia Oxide Bearing Balls
Zirconia oxide balls for low-friction bearings in Czochralski crystal growers, critical for smooth rotation in semiconductor wafer production. HTS 8482.91.0030 applies to these advanced 'other' ceramic balls.
High-Polish 5/32 Inch Carbon Steel Bearing Balls
Mirror-finish 5/32 inch carbon steel balls for lapping machine bearings in wafer preparation, ensuring flatness tolerances in semiconductor processing. Classified as 'other' balls under HTS 8482.91.0030.
Precision 4mm Sapphire Bearing Balls
Synthetic sapphire balls for ultra-precision bearings in semiconductor testing polishers, offering extreme hardness for device processing equipment.
Grade 3 10mm Tool Steel Bearing Balls
High-grade tool steel balls for heavy-duty bearings in boule grinders, precision-engineered for semiconductor crystal processing.
Anti-Magnetic 2mm Bearing Balls
Low-magnetic 17-4 PH stainless balls for cleanroom bearings in wafer fabs, preventing contamination in semiconductor processing.
