Ceramic Hybrid Bearing Separator from China
A high-precision ceramic separator for hybrid bearings combining steel races with ceramic balls, used in ultra-high-speed wafer polishers. Falls under HTS 8482.99.65 as 'other' parts, excluding iron/steel cages and due to advanced material not fitting specific subheadings. Critical for minimizing contamination in semiconductor processing.

Import Tips
• Obtain material safety data sheets (MSDS) certifying ceramic composition (e.g
• silicon nitride) for classification
• Document compatibility with specific bearing types (e.g
• 608 series) to avoid general parts headings
• Watch for ITAR restrictions if used in advanced semiconductor tools; declare technical parameters accurately
