Choose the Right Hydraulic Cylinder
The three most common types of hydraulic cylinders are:
Tie-rod: Most industrial and manufacturing applications use tie-rod cylinders, though they are not generally as strong as welded cylinders. Anywhere from 4 to 20 threaded steel tie-rods are connected to the barrel to keep the two end caps in place, providing extra stability and preventing fluid leakage. The tie-rod cylinder’s advantages include ease of assembly and maintenance.
Welded: A welded rod hydraulic cylinder has end caps that are welded directly to the barrel to close the case of the cylinder. They typically have narrow bodies and shorter overall length, enabling them to fit better in tight spaces, especially in mobile equipment, but they are difficult to assemble and disassemble.
Telescopic: As the name suggests, telescopic cylinders are constructed like a telescope and consist of a series of tubular rods called “sleeves.” The sleeves decrease in size sequentially and are nested inside of one another. Their greatest advantage is their ability to provide an exceptionally long stroke from a compact initial package.
Warning Signs of Hydraulic Cylinder Failure
Hydraulic cylinders that are not properly maintained will eventually fail, sometimes with catastrophic results. Here are the most common causes:
- Contaminated fluid – This is a frequent cause of hydraulic cylinder failure. Foreign particles in the hydraulic fluid can scratch and score the interior of the cylinder and eat away at critical seals and fittings.
- Overheating – A hot cylinder can prevent the system from operating effectively, damage seal compounds, accelerate oil degradation and waste electricity.
- Damaged or bent piston rods or rod bearings – This problem is often caused by overloading the cylinder or by a misalignment between the load and the cylinder. Rough places on the rod can damage the seals, reduce their normal life, and require them to be replaced frequently.
- Broken eye bearing – The eye bearing can break when the cylinder is forced to handle a heavier load than it was designed for or shock loading, which occurs when there’s a sudden impact to full pressure (or beyond) that can be caused by an abnormal load or improper operation.
- Leaking seal – The most common reason for this is an improperly fitted seal. However, corrosion or abrasion of the cylinder seal grooves, oil contamination or entrapment, and incorrect metalwork clearances are a few of the other reasons that seals may leak.
