How To Prevent Cylinder Leakage

Hydraulic cylinders are typically reliable parts, lasting up to several years in heavy machinery. If searching for a hydraulic cylinder or any other machinery equipment at your local ram mount dealership it’s important to make sure that you’re buying only the best product, that won’t cause any problems later down the line.

Today we’ll be going over the steps taken throughout the design, assembly, and maintenance of your cylinder to ensure no leakage or damage will occur.


Manufacturing and Design for Leak Prevention

For design, manufacturing and testing, it’s useful to know what processes your vendor puts in place to ensure quality. Your team should record and document all tweaks and improvements made to your system.

With accurate recording mechanisms, the manufacturer of your cylinder is able to track which design tweaks were most successful over the lifetime of each part, integrating only the best practices that have continually improved its operation and operational life.

The core welding process is one essential step in ensuring that your cylinder has been produced at the highest level possible. The core welding process is a semi-automated process that uses a combination of automation and hand-welding.

This involves creating a chamfer on the steel before the welding process, so that rather than welding two flat surfaces, there is already a fit for the end cap where there is a receiving groove for the material. As a result of the preparation process, welding is easier, and the result is a much more durable product. This process absolutely eliminates welding leaks.


Precision Seals

For a leak-free and high-quality cylinder you’ll require precision seals. You want to ensure that the design of these air-tight seals is still in place even after their installation.



Many manufacturers will use oil testing for hydraulic cylinders leakage tests, this works to replicate the operation setting that they’ll later be used in. Through air testing you can achieve quicker and cheaper results that work better to identify any leaks or breach in your cylinders function, since air can escape places more easily than oil. Because of this simple and clean testing method all pieces of your system can be properly tested to ensure no leaks.

Many manufacturers will also send a sample part for destructive weld testing with microscopic inspection, to ensure that every batch is perfect.


Cylinder Care During Operation

Other than checking your cylinder for any damage it won’t require much maintenance. The only exception is for equipment that is not in regular use, such as fire engines or farming equipment in the off-harvest season. If you have a cylinder that runs seasonally you need to ensure that the shaft is aptly lubricated. A dry shaft is vulnerable to abrasion and moisture, resulting in rust. Simply running the equipment every two or three months to get the hydraulic cylinders moving will lubricate the shaft sufficiently to prevent this problem.
