From auto repair shops to construction crews, professionals across numerous industries use hydraulic equipment to get work done. That's why it’s important to know the warning signs of a failing hydraulic cylinder. Here’s a closer look at three common red flags that point to the need for replacement. 

3 Signs Your Hydraulic Cylinder Needs Replacing

1. Damaged Piston Rod

The piston rod is one of the most important components in a hydraulic cylinder, as it transfers the piston’s energy to the operational component in your machine. If this rod appears warped, buckled, or severely scratched, replacing it will be a much more economical choice than repair. If the cylinder isn’t replaced, the rod will continue to deteriorate and eventually collapse under the piston's pressure. 

2. Worn Mountings 

These fasteners are responsible for holding a hydraulic cylinder in place. However, over time, they may sustain wear and tear, such as rusting or warping. If they get too worn out, they may not hold the cylinder reliably, causing it to shift out of alignment. At the first sign of movement from the mountings, replace the hydraulic cylinder.

3. Leaking Fluid

Hydraulic cylinders are filled with fluid and sealed, but if they're damaged, this fluid may begin to leak out. You might notice the piston rod appears wet or moisture pooling under the gland. Examine the cylinder for the source of the leak. If the opening is substantial, it’s in your best interest to replace the cylinder altogether.
