How many type hydraulic cylinder do you know?

There are many different types of hydraulic cylinders available that are designed to work within specific applications. Below is the most common hydraulic cylinder types.

The Basics

A hydraulic cylinder is an actuator that creates linear movement by converting hydraulic energy back to a mechanical movement. Cylinders are made up of a steel barrel, a piston connected to a piston rod that moves back and forth, and mounting accessories. They are used in equipment to lift, push, pull and press loads that require exceptional force.

Available in several different body styles, including tie-rod, welded and telescopic, hydraulic cylinders can be single-acting or double-acting.

1.Single acting hydraulic cylinder: In a single acting hydraulic cylinder, piston force is applied in a single direction when pressurized oil extends the rod. Once the oil is exhausted, gravity and the load return it to its natural position.

2.Double acting hydraulic cylinder:Double-acting cylinders can exert force in two directions. The piston cylinder is divided into two pressurized chambers that enable the rod to achieve both outward and return strokes. Pressurized oil allows the rod to move in either direction.

3.Tie-Rod hydraulic cylinders: Tie-rod hydraulic cylinders use high strength threaded steel rods to hold the two end caps to the cylinder barrel. They are held together by four or more threaded tie bolts that run the length of the entire cylinder tube. These bolts hold the baseplate and head together. They usually have static seals to prevent leakage between the barrel and end-cap interface. Tie-rod cylinders are best for medium to light-duty mobile applications. Their cost of ownership is lower, since they are easier to assemble, maintain and repair.

4.Welding hydraulic cylinders: In a welded hydraulic cylinder, the barrel is welded to the end caps rather than using steel rods. Static seals are used to seal the head or gland of a welded cylinder. Welded body cylinders have many advantages over tie-rod cylinders, including a compact design that usually can withstand higher pressures, often greater than 5,000 psi. Because of this, they are often used on mobile machinery where space is at a premium. Their rugged design not only makes them ideal for extreme weather and operating conditions, but also contributes to much longer service life than tie-rod cylinders because they do not fail due to tie-rod stretch at high pressures and long strokes.

5.Telescopic hydraulic cylinder(multi stage): Telescopic cylinders are several individual cylinders (like the sections of a telescope) nested together in order of decreasing size. Because this style of cylinder is able to extend from its compact design, it provides an exceptionally long stroke. The collapsed length of a typical telescopic cylinder varies between 20% to 40% of its extended length. In general, telescopic cylinders are single acting and are available in two to five stages. They are frequently used in trucks in the construction industry, vehicle trailers, garbage and dump trucks, as well as in the agricultural industry.
