When Should a hydraulic cylinder be replaced?
When to Replace Your Hydraulic CylinderHydraulic cylinder no longer works or functions properly.Hydraulic fluid is leaking from the cylinder.Hydraulic cylinder seals are worn or broken.
Why do hydraulic cylinders leak?
Hydraulic cylinders may also leak as a result of over-tightening of the seal upon construction , this will lead to cracks in the build of the cylinder, ultimately damaging performance, and again posing as an invisible problem. It is vital to ensure that hydraulic cylinders are properly fitted, and regularly lubricated, this will minimize the chances of future leakages occurring.
How to tell if a hydraulic cylinder is leaking?
Almost all hydraulic cylinders will show the same signs of a leak, if you understand the theory behind it, it’ll be much easier to notice the problem. When the hydraulic fluid leaks through the worn or faulty seal, the pressure between each region will change, when this happens, the motion of the rod is affected, as there is an uneven balance of fluid between each region. When the rod in the cylinder is set to move and return, you will notice that the fluid dispersion will cause the cylinder rod to slowly slide back into the open position.
How does hydraulic fluid seep into a hydraulic cylinder?
The hydraulic fluid will seep through the cracks and enter the opposing region , this is likely to drain the cylinder of energy and isn’t at all visible from the piece of machinery itself. It isn’t until operational managers and staff notice the drop in performance, that they realize there is a problem with the hydraulic cylinder. As the fluid is maintained inside, there isn’t a way to stop internal leakages without being equipped with the necessary tools for the job. A fluid leak of this kind can be referred to as a “leak down”, as the oil leaks down into the piston region of the cylinder.
Why invest in a hydraulic cylinder?
Investing in a cylinder with high-quality connectors is vital to prevent leakages, cheap and short-life connectors will have a noticeable difference to high quality, branded cylinder components, and connectors. When leakages occur due to poor connectors, operational managers can often be hesitant to allow time for repairs. Maintenance is costly, and these kinds of businesses generally cannot afford a prolonged length of downtime, if the hydraulic cylinder is still creating results, managers will generally choose to keep the machine running, just because it costs less.

What causes a hydraulic system to fail?
Also keep in mind that if fluid can leak out, contaminants can make their way in. Contamination is one of the most common causes of hydraulic system failure and should never be treated lightly.
How to protect hydraulic system from contamination?
Protect the system from contamination once you have opened it by carefully cleaning the connecting ends of the fitting before you install it. Remember that shards or flakes of metal, dirt, and fibers from cleaning rags often enter hydraulic systems during routine maintenance, but the chances of this can be minimized by using non-shedding rags that have been carefully cleaned prior to use. The type of damage that contamination can cause is expensive and, if not caught soon enough, can be irreparable.
