Double-rod cylinders are cylinders with a continuous piston rod and therefore have two working areas of equal size for extending and retraction.
Due to the continuous rod, the overall length of such cylinders (also called double-acting cylinders) is approximately twice as long as that of cylinders with a single-sided piston rod.
By installing air filters, double-acting double-rod cylinders can be used as single-acting cylinders - for tension or compression.
