A tandem cylinder is one in which two or more piston and rod combinations are assembled as a rigid unit with all pistons mounted on single rod.
TANDEM CYLINDERS • A tandem cylinder is one in which two or more piston and rod combinations are assembled as a rigid unit with all pistons mounted on single rod. • Such cylinders are designed to provide a large working area and thus large forces for a given pressure for a small cylinder diameter. • These cylinders are used to obtain a low-force, high-speed action followed by a high- force, low-speed action. Fig.5.6 illustrates a stepped-tandem cylinder, in which two pistons of different sizes mounted on one rod. It contains two cylinders that slide inside each other. Since two cylinders are arranged in series, the tandem cylinder produces the large force (almost double). However, its drawback is that they occupy more linear space. The another modification of tandem cylinders is the dual cylinder designs. A dual linear actuator is shown in Fig.5.7. The piston and rod assemblies of a dual actuator are not fastened together as in the tandem actuator. In most dual actuator designs, a given piston acts on another only in one direction.1.
