High-Speed Ceramic Hybrid Ball Bearing from Germany
Ceramic hybrid ball bearings with steel races and ceramic balls for float zone crystal pullers in semiconductor wafer manufacturing, offering extreme purity and heat resistance. Under HTS 8482.10.5068 as other ball bearings, they enable contamination-free rotation during monocrystalline boule growth via Czochralski methods. Essential for slicing ultra-flat wafers without defects.

Import Tips
• Certify ceramic material composition to distinguish from all-steel bearings in tariff notes
• Use cleanroom packaging and declare vacuum compatibility if applicable
• Monitor Section 301 tariffs if sourced from China, common for hybrid bearings
