Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If integral to boring/sinking machinery
If specifically for boring or pile-driving equipment, classifies under parts of that machinery.
If non-tie-rod construction
Welded or bolted cylinders (not tie-rod type) use the other linear acting cylinder subheading.
If valve-integrated design
Cylinders incorporating control valves become hydraulic valves rather than linear motors.
