Trelleborg Releases Extended Hydraulic Systems App

Trelleborg Sealing Solutions is continuously updating its most successful engineering apps and has released an extended Hydraulic Systems Calculator app. Free of charge to download, the app is an easy-to-use tool and now supports the design of the complete hydraulic system.
Claude Kornelis, Director Digital Business Development at Trelleborg Sealing Solutions, says: “Our Hydraulic System Calculator app was designed with the engineer in mind. Though an engineer may be an expert in hydraulic applications, they may require support with sealing and that’s what the app provides.

“For us at Trelleborg Sealing Solutions, it’s all about providing tools that make the working lives of engineers easier; whether at their desks or on the go, 24/7. Though this is not a unique tool, unlike others it is completely free of charge.”

The original Hydraulic Cylinder Calculator App was released in 2014 and since then has had over 80 thousand downloads and become the third most popular Trelleborg Sealing Solutions app. The update means that four new modules have been added and the app can now support in the design of the whole hydraulic system rather than just its cylinders.

By entering the required dimensions of the cylinder and parameters like pressure and oil flow, calculate areas, volumes, acting retraction forces, velocity, time, outflow and ratio in the cylinder, the tool can provide parameters for design of motors, pumps and pipes for both the piston and rod side of the cylinder


The calculator is very user friendly and dynamically updates results as values are keyed in. Calculations can be carried out in both metric or inch measurements, while input and output values can be displayed in preferred sub-units after the calculation is carried out. The app also helps the user make specific unit changes prior to calculations.

Interactive images in the cylinder section enable a better understanding of the component and dimensions can be confirmed to ISO 3320, ISO 3321 and ISO 4393. Results can be copied to a clipboard and shared via e-mail.

The app can be downloaded for iPhone or Android by searching for Trelleborg Hydraulic System Calculator in iTunes or Google Play.

The Hydraulic System Calculator App is just one of a number of best-in-class tools Trelleborg Sealing Solutions offers to make it easier for engineers to specify seals for their applications. It joins the ever popular Unit Converter and already well-established O-Ring calculator, electronic catalog, CAD service and e-learning modules, as well as the recently released Fluid Mechanics Calculator. All are available free of charge via a registration area on the Trelleborg Sealing Solutions website. Go to to find out more.
