Stopper cylinder ST series

pneumaticmagnetic pistondouble-acting

The Series ST Stopper cylinders are pneumatic actuators with rod, complying with UNITOP and ISO 21287 standards, where rod and bushing have been specifically enlarged to ensure high resistance to radial loads and shocks. These cylinders are available in two versions, double-acting and singleacting, and with rear spring. The nonrotating rod version is also available. The detection of the piston position is enabled by means of proximity switches (Mod. CST or CSH) which are mounted in slots along three sides of the cylinder profile. It is possible to cover the slots with a proper profile (Mod. S-CST-500). The high resistance to shocks and radial loads and the easy mounting makes Series ST particularly suitable for use in transport/conveyor lines where it is required to stop the transit of workpieces and workpiece-holder pallets.
