Round cylinder ISO 6432

Double-acting

Double-acting round cylinders to ISO 6432 generate force in both directions of travel and are used wherever both push and pull force is required. The range includes Airtec cylinders types ZD and ZDM with bore diameters from 10 to 25 mm and strokes from 10 to 160 mm. ISO 6432 standardisation ensures that bore diameters, threads, port dimensions and mounting points are cross-manufacturer compatible, simplifying replacement of individual cylinders in existing installations.
