What Is a Telescopic Cylinder and
How Does It Work?
A telescopic cylinder is a kind of a hydraulic cylinder which has different
pipes or sleeves fitted into one another. It is also referred to as a multi-stage
cylinder which is a type of linear actuator consisting of different sleeves. The
sleeves are built inside one another, normally four or five, and keep
decreasing in diameter. These sleeves or cylinders enable you to increase the
output of speed and force when used in industrial projects.
Construction of a telescopic
It consists of a number a number of cylinders, which decrease in size, that are
built into one another. The main cylinder accommodates the rest of the
cylinders placed inside one another. The main inlet for hydraulic fluid to
enter the cylinder is provided on the outermost cylinder, with inlets also
provided on each subsequent sleeve.
How does it work?
When the hydraulic fluid enters the outermost cylinder, it pushes the cylinder
no.2 in an upward direction after enough fluid pressure is generated. After
cylinder no.2 is completely lifted, fluid enters the inlet of this cylinder. Once
the oil enters cylinder no.2 and flows through it, it pushes the piston in an
upward direction. It then raises the piston for stroke length of cylinder no.2.
The benefits of using telescoping
Ideal for applications with space
If there is limited mounting space available in your application and yet
require long strokes then hydraulic telescopic cylinders are the best for you.
They are compact devices and are capable of extending beyond the collapsed
length. It can extend in both directions in case of a double acting cylinder. To

Capable of achieving specific angle
There are a lot of applications that require specific angle requirements, like a
dump truck. To be able to unload the materials, the angle requirements can be
very specific. Generally a telescopic cylinder n
