Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for non-rotary offshore boring
Offshore boring excluding rotary mechanism uses adjacent statistical suffix.
If imported as rig parts
Tables for assembly into rigs classify under parts of boring/sinking machinery.
If clutches emphasized over rotation
Clutch assemblies in rotary tables may classify under transmission clutches.
