Hollow Plunger Cylinders

A center hole makes hollow-plunger cylinders useful when a rod or cable must pass through the tool to transmit pulling or tensioning force. Belium lists single- and double-acting hollow cylinders, including aluminum versions, for applications such as component extraction and rod tensioning. Bore clearance is a key selection dimension alongside force and stroke: the cylinder must accommodate the pulling member and its attachments. Check the complete assembly, rather than choosing by tonnage alone.
