Hydraulic rod cylinders play an integral role in helping mechanisms function. They’re used across almost every industry in some way, and there are several types to choose from. It’s important to understand what they do and their applications. This ensures you purchase the right parts for your needs and get the best use from your machinery.

4 Hydraulic Rod Cylinders & Their Applications

1. Single & Double Acting

Single-acting hydraulic rod cylinders use pneumatic or hydraulic pressure to control a piston. A reacting force, such as gravity, then returns the piston to its original position. Double-acting cylinders use water and pneumatic pressure to both retract and push the rod outward and are more common. You’ll find each used in manufacturing presses and construction machinery.

2. Welded Rod

Welded rod cylinders are secured to end caps in machinery rather than threaded in. This creates a more secure connection that can also increase the power and length of a stroke. It’s also found on construction and heavy-lifting equipment and used in civil and manufacturing capacities.

3. Tie Rod

Tie-rod hydraulic rod cylinders are threaded into end caps rather than welded. Several are usually used together to generate significant power. Because of the threading, they’re easy to remove and repair as needed when compared with welded or acting cylinders. They’re extremely common, and you’ll find them in manufacturing and construction equipment.

4. Telescopic

Telescopic cylinders are ideal when a long stroke length is needed. They consist of steel tubes contained within one another that slide out and lock as the stroke increases. This convenient design ensures they don’t take up much space while retracted—without sacrificing stroke length. You’ll often find them on construction equipment and cranes with movable arms.
