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.

For more information on hydraulic cylinder maintenance, we suggest visiting or reviewing the product literature provided with any cylinder purchased. We hope you found this post informative, please check back for new postings.

Hydraulics 101: What is the Stroke of a Hydraulic Cylinder?

Welcome to the 2nd installment of Hydraulics 101! So what is the stroke of a hydraulic cylinder?

hydraulic cylinder strokeThe stroke is one of the more commonly confused terms when it comes to hydraulic cylinders. The stroke is actually the distance the cylinder can travel, from fully closed to fully open. When someone is talking about a 30″ cylinder, they aren’t (or shouldn’t be) talking about the overall length of the cylinder, but they should be talking about how far it will lift or move something. The basic description of any cylinder is BORE & STROKE, so a 2.5 X 30 hydraulic cylinder has a 30″ stroke, meaning it will lift or push something 30″.

If you aren’t sure what the stroke of your cylinder is, subtract the length “fully closed” from the length “fully open”. Easy enough?

I hope this helps & as always, feel free to comment or send us an email with any other questions!

Hydraulics 101: What is the Bore of a Hydraulic Cylinder?

Sometimes we talk about things in a way that makes perfect sense to us, forgetting that it may not make a lot of sense to people that are not “in the business” of our industry. So I’m starting this new series of posts for those new to hydraulics & hydraulic cylinders in particular. We will try to keep the posts short, to the point, easy to understand & informative.

So, what is the “Bore” of a hydraulic cylinder & why is it important?
The bore is simply the INSIDE DIAMETER of the tube of the cylinder.

The Bore of the cylinder determines the total power of the cylinder. The larger the bore, the more it can lift or push. If you see or hear us talking about a “4 inch” cylinder, we are always talking about the bore of the cylinder. The outside diameter (OD) is usually about 1/2″ larger than the bore, but it depends on the wall thickness, so if you measured your cylinder from the outside and it measures 4-1/2″, you can be pretty sure its a 4″ Bore cylinder.
