Various Types of Hydraulic Cylinders

The power of hydraulics can deliver ten times the energy of electric motors. Fluid power applications are great for pulling, pushing, and lifting huge loads. Today, modern technology permits it to be controlled precisely, and the security aspects of this technology make it an even more compelling piece of equipment.

Hydraulic power systems are frequently used in various industrial applications. They are also being developed by incorporating new technologies. Hydroline is thrilled to revolutionize this two hundred years old technology. Our experienced team of engineers is constantly working to improve the technology and to provide tailored solutions for your business.

Different kinds of hydraulic Cylinders

There are a variety of hydraulic cylinders that one might come across. Hydraulic cylinders are typically employed in situations that require massive loads and require a large quantity of power. Hydraulic cylinders can be simple, sturdy, and durable. They also generate an enormous amount of force than mechanical, pneumatic as well as electrical systems. A hydro pump is about ten times the power of an electric motor’s equivalent size. A wide selection of cylinders satisfies the broad spectrum of industrial needs.

The selection of the correct Cylinder for the application is vital. It is a matter of taking into consideration different factors. There is a good array of cylinders, mounting methods, and “rules of thumb” available to help you.

Single-acting hydraulic Cylinder

Single-acting cylinders can only operate in one direction. Therefore, there is only one access port to the Cylinder. The port is situated at the end of the Cylinder. It only functions in only one direction. When oil is introduced into the port presses the rod and causes it to stretch. 

It then retracts to an external force, such as a load or spring. As the oil moves through the port, it is compressed on a plunger, triggering the motion. When the Cylinder runs out of fluid, the plunger will return to its position.

Hydraulic pancake Cylinders

Hydraulic pancake cylinders are actuators that are employed in industrial applications for creating linear motion. The name itself suggests that they are round and flat in form and resemble the shape of a pancake.

The cylinders comprise the barrel of a cylinder with a piston, rod, and port to hold hydraulic fluid. When the pressure of hydraulics gets applied to the port, it pushes the piston, which then causes linear motion. The pancake design makes it possible to create an extraordinarily compact and low-profile actuator that can exert a large quantity of force in the smallest space.

Double-acting hydraulic Cylinders

Contrary to the single-acting one, the double-acting one has two ports. One to extend the plunger and the other to retract the plunger. These ports are situated at the opposite ends of the Cylinder; the head and the rod. Both ports are utilized when retracting the rod and when the rod is extended. One port on the head’s end is employed.

Double-acting cylinders offer a significant advantage over other kinds of cylinders. A lip on the ram lets the rod be supported inside the Cylinder throughout the lengthening and retracting procedures.

Ram-type actuator piston

Telescopic cylinders are made up of the use of aluminum or steel tubes with decreasing diameters nested within one another. Telescopic cylinders may be single – or double-acting. Telescopic cylinders generally are more costly than standard cylinders. 

The majority of telescopic cylinders are single-acting and double-acting. Telescopic cylindrical are custom-designed and produced. Telescopic Cylinders are multi-stage units with 2 or 3 steps.
