Monocrystalline Wafer Lapper Bearing
A monocrystalline wafer lapper bearing is an angular contact bearing engineered for wafer lapping machines used in semiconductor fabrication. It maintains precise dimensional tolerances during the lapping process, ensuring uniform wafer thickness. This bearing is classified under tariff item 8482.80.00 as an 'other' bearing, including combined ball/roller bearings, because it is not a standard ball or roller bearing but a specialized variant.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the bearing is a standard ball bearing without specialized wafer lapping design
Ball bearings are classified under 8482.10.00 when they are not combined with rollers or specially adapted for other functions.
If imported as a part of the bearing rather than a complete bearing
Parts of bearings are classified separately under 8482.99.00 when they are not integral to a complete bearing.
