Industry Uses for a Hydraulic Cylinder

There is a wide range of apparatuses of large automated systems and machinery that has been developed throughout the years in order to make things operate more efficiently and smoothly. Amongst the apparatuses, a hydraulic cylinder is also included. This component is a mechanical actuator, which produces unidirectional force via unidirectional stroke. A hydraulic cylinder has several applications, which are mainly based around construction equipment. Read on and discover the many instances where a hydraulic cylinder tends to be most valuable.


These devices are used a lot within agricultural industries, and can be used for a range of machines including loaders, harvesters, and tractors. In addition, they may also be used as attachments for hydraulic wood splitters, tractors, and more.

Civil Engineering

The civil engineering industry also calls for these devices for their machinery, as bulldozers, trenchers, excavators, and their attachments all feature hydraulic cylinders.

Energy Industry

These components also seem to come in useful for the energy industry. Hydroelectric stations that have gate controls make use of these cylinders, as these cylinders help with the possibility of opening and closing gates to control water flow.

Mechanical Engineering

Mechanical engineering also values these cylinders, as they come in extremely handy for automated production lines, forming machines, feeding devices, producing ecological equipment, transportation devices, and plastic forming machines.


Finally, shipbuilding is another industry that values the device. Hydraulic cylinders can be found in steering mechanisms, hoists, transportation equipment, and more.


Many other industries that value the device include automotive, aeronautical, food, and construction. With the wide range of uses for hydraulic cylinders, having only one kind of this device can make things very difficult. This explains the several variations of the component. This ensures all the roles are undertaken correctly and the right type of the device is being used. The variety includes single-acting, double-acting, telescopic, and plunger cylinders.

Even though there are a couple of variations, they all feature the main components: the piston and barrel. Further components include the head, base, piston rod, deals, welded port, flange, rod end, bearings, bushes, and other small parts. A manufacturer of hydraulic cylinders puts these components together in order to make the device function properly.



Different Types of the Pneumatic Cylinder

A pneumatic cylinder is a type of appliance that makes the use of power that is generated from compacted gas in order to form a force in interchanging linear motion. A pneumatic cylinder may also be referred to as an air cylinder, as the term pneuma, means air. Very similar to hydraulic cylinders, a force is applied into the piston, which pushes it to the desired direction. The piston that is part of a pneumatic cylinder is a disc or a cylinder. The force that is created is transported by the piston rod to the object that requires moving. A minority of engineers prefer this device due to its cleanness, quietness, and minimum space for storing fluids.

Purpose and Type

The shape, material, and size of the cylinders depend on the purpose one is using them. The different materials that are used for pneumatic cylinders include stainless steel, steel, nickel-plated brass, and aluminum. The way the materials are chose for the devices involve considering several factors such as amount of loads, specific stroke length, temperature, and humidity. The devices also come in a wide range of body constructions, which include:

  • Flanged- type cylinders – the ends of these cylinders feature fixed flanges.
  • Tie rod cylinders – these are the most common type of cylinder structure and find their use in a huge variety of loads. These are also proven the safest form to work with.
  • Threaded end cylinders – in these, the ends tend to attached to the tube body.
  • One-piece welded cylinders – the ends of these cylinders are welded or crimped to the tube.

A Further Look into the Types

The three pneumatic cylinders we discuss below are:

  • Single-acting cylinders
  • Double-acting cylinders
  • Telescoping cylinders

Single-acting cylinders (SAC) use pressure that forms from compacted air. In majority of cases, the extension SAC cylinders have is very limited due to the amount of space the compacted spring takes.

Double-acting cylinders (DAC) use air pressure in order to retract strokes and move in range. Two parts make up this cylinder, both of which let the air in. One is for outstroke and the other, in-stroke.

Telescoping cylinders, also known as telescopic cylinders come in single-acting and double-acting modes. Their designs allow for much longer strokes and tend to be reserved for uses where the piston has to face minimal side loading.
