What is Tandem Cylinder | Construction, Working, Symbol
Definition
When two double acting cylinders are mounted in line with the pistons connected to a common piston rod, It is known as tandem cylinder.
Construction
It consists of two double acting cylinders joined with the common partition as shown in below figure.
construction of Tandem cylinderIt consists of two or more cylinders arranged one behind the other but designed as a single unit. This type of actuator cylinder is used in applications that require two or more independent systems. Fluid flow to and from the two chambers of the tandem cylinder comes from two independent hydraulic systems and is controlled by two sliding spool directional control valves.
The pistons are connected to a common piston rod. The four ports are provided (two inlet and two outlet ) which includes two ports of each double acting cylinder.
It has more linear dimension compared to simple double acting cylinder. Hence occupy more linear space.
Working
When oil enters in the cylinder 1, it produces force F1 and when enters in the cylinder 2 at the same time produces F2.
Hence at the piston rod, we can get double force (F1+F2) during movement of pistons.
Similarly for the return movement of the piston, we can get double force.
Pressure is applied to both pistons, resulting in increased force because of the larger area.
Symbol
Application
A tandem cylinder is used, where a large amount of force is required from a small- diameter cylinder. It also used if the space provided is not sufficient for a normal cylinder.

FAQ
- What is the tandem cylinder?
- When two double acting cylinders are mounted in line with the pistons connected to a common piston rod, It is known as tandem cylinder.
- Where is Tandem cylinder used?
- A tandem cylinder is used in applications where a large amount of force is required from a small- diameter cylinder.
- How does a tandem cylinder work?
- Tandem cylinders use multiple pistons connected through a common rod to generate relatively high force from a low supply pressure and small bore. … For example, a tandem cylinder uses two or more pistons connected to a single piston rod to multiply force produced by a cylinder without increasing bore size.
