Precision Radial Ball Bearing for Wafer Crystal Pullers from China
This high-precision radial ball bearing is designed for use in crystal growers and pullers during semiconductor wafer manufacturing, supporting rotating shafts under ultra-clean conditions. It falls under HTS 8482.10.5064 as a radial ball bearing not specified elsewhere. Its low-friction and contamination-resistant design ensures smooth operation in Czochralski method crystal growth equipment.

Import Tips
• Obtain material certificates confirming low-particle generation for cleanroom compatibility in semiconductor fabs
• Verify bearing precision class (e.g
• ABEC 7 or higher) matches equipment specs to avoid reclassification
• Include end-use statements proving semiconductor application to qualify for potential duty exemptions
