HUMPHREY BLOCK CYLINDERS TANDEM CYLINDERS HJDAT
Humphrey Block Cylinders Tandem cylinder HJDAT are useful where extra force is required. The tandem cylinders are cylinders incorporating 2 cylinders with individual ports, one behind the other where the piston rod of the rear cylinder pushes against the piston of the front cylinder therefore creating nearly double the force. The tandem cylinders can also be used as a multi-position actuator by operating the cylinders independently. Available bore sizes are 12mm through 100mm with longest combined stroke of 4″.
