Hydraulic rod cylinders are devices used in a variety of applications, including heavy construction equipment, industrial machinery, and civil engineering. Despite their major role in streamlining the manufacturing process, they still remain a mystery to many people. Here is a comprehensive guide to how hydraulic rod cylinders operate to see how they make the manufacturing process easier.

What Are the Components of the Hydraulic Rod Cylinder?

Cylinders are designed to produce great amounts of force and linear motion. This is done through several major components within the cylinder, which are the piston, rod, head, and base. Pressure is exerted on the surface area of the piston; the larger the diameter of the cylinder, the more force it can produce. The piston must be equipped with a seal to build up the required pressure and prevent it from slipping. The rod, or the shaft of the cylinder, is designed to protect against fluid and pressure leakage. It extends through the head of the cylinder and connects to the piston at the base end. 

How Does a Hydraulic Rod Cylinder Work?

There are two main types of cylinder configurations—single and double acting. In a single-acting cylinder, pressurized fluid is routed to either the rod or cap end to extend or retract the cylinder. In a double-acting cylinder, pressurized fluid moves into the rod end, which causes the piston to retract. When it moves into the cap end, the piston will extend. This makes it possible for excavators, backhoes, and other construction equipment to push, pull, or lift extremely heavy material with ease.
