Semiconductor Wafer Lapping Machine Outer Bearing Race from Canada
Outer race optimized for cylindrical roller bearings in lapping machines that achieve ultra-flat wafer surfaces for semiconductor device fabrication. Withstands abrasive slurry conditions while maintaining sub-micron precision. HTS 8482.99.2560 applies to such other cylindrical roller bearing outer rings.

Import Tips
• Document corrosion resistance for slurry environments to support semiconductor processing classification
• Provide equipment OEM specifications linking race to identified wafer lapping apparatus
• Ensure no pre-installation; loose races classify separately from assembled bearings
