Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If matching specific matched-set criteria for high-speed applications
Matched bearing sets for high-speed operations are separated in 8482.10.10, not general 'other'.
If considered a plain shaft bearing rather than ball type
Slide bearings without rolling elements fall under 8483, based on design not semiconductor use.
If imported as part of semiconductor wafer preparation machinery
Complete or sub-assemblies of semiconductor processing machines are in 8479.50, not individual components.
