A hydraulic cylinder uses pressurized fluid to generate linear force and motion. These crucial parts are frequently used in construction and industrial settings to power dump trucks, bulldozers, backhoes, and other equipment. Below, learn about three common types of cylinders and the benefits of each.

A Guide to Hydraulic Cylinders

1. Single-Acting

In a single-acting cylinder, force is applied in one direction. Fluid gets pumped into the barrel and the piston rod, and an external force or a load string generates the return operation. Then, the liquid is drained from the container into the reservoir using external energy. 

These cylinders are simple and straightforward to use, easy to maintain, and economical, as they require only one hose per cylinder. They're often used for clamping, hydraulic rams, and positioning products on conveyor belts.

2. Double-Acting

Double-acting cylinders apply force in two directions at once. The piston-cylinder contains two pressurized chambers, giving the device its own power to move the rod in both outward and return motions.

It uses a specific type of hydraulic fluid, which is pumped to both sides of the cylinder. A double-acting variety offers enhanced precision and faster retraction, making it particularly handy for repetitive tasks. Its dual action is ideal for applications that require the cylinder to be upside down, like presses.

3. Tandem

Tandem cylinders have two separate barrels linked by a single rod attached to a piston head in each container. After pressure moves into the first barrel, the rod enters the base of the attached cylinder and drives the piston, thereby relaying the needed force. These options are excellent for preserving energy in larger equipment, like forklifts, cranes, and crop spraying implements.
