Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cross-section 12.7mm or greater
Larger wire diameter helical springs have a separate statistical breakout.
If for specific conveyor machinery parts
If designed exclusively for conveyor equipment, may classify under parts of lifting/conveying machinery.
If imported as pump component
Helical springs integral to pumps classify under pump parts rather than generic springs.
