What Types Of Hydraulic Cylinders Are There?

3 min read

Most hydraulic cylinders are based on the fundamental idea of delivering linear force over a single stroke. A hydraulic pump drives the piston in the device, either pushing or pulling the rod in the direction you wish. Hydraulic cylinder jacks, also known as hydraulic jacks or hydraulic lifting cylinders, are powerful devices used for lifting heavy loads with ease and precision. The benefits you’ll reap through your hydraulics system are contingent on the kind of cylinder you select.

Single Action

One of the simplest types of hydraulic cylinders, Single-action cylinders, can be designed to pull or push in a single-action hydraulic Cylinderssingle direction. A different method is an anti-weight, a spring, and even gravity will force it back towards its original position.

These single-action hydraulic cylinders can save costs while requiring lesser porting and hydraulic hoses. This makes them one of the most straightforward to incorporate into standard systems.

Besides the fact that you can only pull or push in one direction, the main drawback to single-acting pistons is that you have to vent the opposite aspect of where you are applying pressure.

Double Action

To perform more complicated tasks, double-acting cylinders draw and push the cylinder’s piston to give Double-Acting Hydraulic cylinders greater quantity in linear force. In this case, hydraulic pressure is applied to the two sides. This allows the usual back and forth associated with hydraulic power.

A majority of applications require the more excellent performance of double-action hydraulic cylinders. It is generally simpler to use with dual-action cylinders, and it’s simpler to regulate the system’s movements.

But, for those situations that require a steady output and speed, there’s a chance to run into issues with conventional double-action pistons. Because you’re typically pumping different amounts of oil to one side than the non-rod sides of the cylinder, the piston extends at a slower pace than the speed at which it retracts.

Position Sensing Cylinders

In any cylinder, you can include sensors in the design to increase stroke control and programming. “Position-sensing cylinders” or “smart” cylinders are cylinders with built-in sensors.

Regular cylinders expand or retract in response to pressure input. By adding a sensor to your cylinder, you can detect the piston’s location at any moment.

The feedback is then sent to a control unit, which can alter the movement of the piston to suit. In time, you’ll be able to utilize this feedback and set up your controller to make the cylinder repeat specific stroke patterns that correspond to the precise functions of the machine. Additionally, you can modify the stroke of the cylinder in response to particular situations. This is especially useful when working autonomously, in subsea conditions, and using large mobile equipment.


If you have an application like the power-steering example presented above, you’ll want to do it with a Double-Ended Hydraulic Cylindersdouble-ended cylinder. Double-ended cylinders can be described as a form of double-action cylinder with rods extended out on both sides of the cylinder. They also have equally sized hydraulic fluid on both sides.

These cylinders provide a consistent flow rate but can reach speeds similar to the regular double-action cylinders. Because of the design inherent to double-ended cylinders, there’s no reason to buy a pump that can handle things such as power steering. | Newsphere by AF themes.
