Series 31

Series 31

Double-acting, magnetic
ø 12, 16, 20, 25, 32, 40, 50, 63, 80, 100 mm
The compact dimensions allow Series 31 cylinders to be installed within very small spaces. These cylinders are suitable for use with feet, flange and trunnion mountings.

In order to complete the compact cylinder series, two new versions have been introduced: tandem and multi-position.
The new Tandem version with 2, 3 or 4 stages generates a thrust force which is 2, 3 or 4 times that of the normal cylinder (standard traction force).
The Multi-position version allows a maximum of 3 different positions which are determined by the stroke of the individual actuators.
