Precision Angular Contact Ball Bearing
A precision angular contact ball bearing is a high-accuracy bearing designed for semiconductor wafer grinding machines, capable of handling both radial and axial loads at high speeds. Its precision construction ensures minimal runout and vibration, critical for wafer surface quality. This bearing falls under tariff item 8482.80.00 as an 'other' ball bearing, as it is not a standard radial ball bearing but a specialized angular contact type.

Import Tips & Compliance
• Classify the bearing under 8482.80.00 only if it is specifically designed for semiconductor wafer grinding; otherwise, standard ball bearings fall under 8482.10.00
• Provide technical specifications, such as contact angle and precision grade, to support the classification
• Consider whether the bearing is part of a larger machine; if so, it may be classified with the machine under Section XVI rules
