Rough Chrome Steel Radial Ball Bearings for Wafer Slicing Saws from Canada
Unground chrome steel radial ball bearings support the high-speed spindle in wafer slicing saws that cut monocrystalline boules into semiconductor wafers. Classified under HTS 8482.10.50.04 due to their unfinished, unground state before final machining. These bearings enable precise slicing essential for semiconductor wafer preparation.

Import Tips
• Provide engineering drawings showing unground tolerances to distinguish from finished bearings under 8482.10.50.40
• Include end-use statements linking bearings to wafer slicing equipment per statistical notes for proper Chapter 84 treatment
• Avoid misclassification as semiconductor testing parts (9031) by documenting fabrication process application
