Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for general grinding machines
Spindles for non-semiconductor grinders classify under machine tool parts.
If crankshafts or plain bearings only
Individual bearing components separate from full spindle assemblies go to transmission parts.
If industrial furnace-related
Heat processing equipment parts may classify under Chapter 84 ovens/furnaces.
