Maintaining Your Hydraulic Cylinder

Hydraulic cylinders are very simple and provide us with solutions to run our equipment and operate at full capacity. You do not want your equipment to fail when you need it the most. Below are our steps to maintaining your hydraulic cylinder:

  • A common reason for hydraulic cylinder failure is having contaminated oil in the cylinder. High-efficiency filters in your hydraulic system are a great way to ensure the oil entering the cylinder is clean. Make sure to check your filter regularly to prevent clogging and also to prevent debris from travelling inside the cylinder.
    It is important to inspect your hydraulic cylinder before each use and develop a regular maintenance plan.
  • Exposing your cylinder to heavy moisture can lead to corrosion which can be the downfall of your entire hydraulic system. Rod corrosion can lead to damage of the seal. If possible, it is best to have a few cylinders to rotate, so that you can clean and maintain your cylinders effectively. When a cylinder is in pieces, it is a great time to replace all seals. Also, take a look at the internal surfaces in the cylinder to observe for any unusual wear.
  • The brackets, clevises, and other connections are just as important as the cylinder itself. You should monitor these joints and observe for wear which can lead to misalignment in your cylinder. If you find that there is uneven wear on your rod, it is most likely caused by misalignment. If there is a load on one side only, it’s going to accelerate the wearing of the seals, bearing and of course, the rod itself. Misalignment can affect the whole cylinder and cause significant damage.
  • When storing your hydraulic cylinder it is best that it is kept in a cool, dry area. As easy as it is to leave your cylinder outside, it is better to keep it indoors with the rod fully retracted. Plug all service ports with steel plugs rather than plastic.
