Higher, Faster, Longer

As airplane designs focus on flying at higher altitudes and speeds for longer periods, the many hydraulic systems onboard must adapt. Today's conditions can include temperatures above 600°F (315,5°C), temperatures as low as -65°F (-54°C), and pressures up to 5,000 psi (345 bar)

As the world attempts to reduce its dependence on fossil fuels, biofuels are now a reality.  Brazil and the U.S. were early adopters of this alternative fuel for transportation but now its use is expanding in Europe, with Germany, France and Spain leading the way.

Trelleborg's tensioner cylinder seals exceed 20-year lifecycle rating

By Mary Gannon

Seals used in offshore rig tensioner cylinders must meet the same rigorous lifecycles as the cylinders themselves. Because offshore environments are harsh and installation and maintenance can be difficult, tensioner cylinders must have a 20-year life. That was why, more than 20 years ago, Trelleborg Sealing Solutions conducted research, determining that its seals could last this necessary lifecycle.

Perfluoroelastomer (FFKM) elastomers offer exceptional thermal stability, outstanding long-term compression set and almost universal chemical compatibility – delivering long life in the most aggressive of media, including hydrocarbon and aqueous media, common within oilfield applications.

Looking Beyond Chemical Compatibility Charts: Matching Plastic and Elastomer Seals with Fluids

By Lucy Heyduk and Tim McCulfor, Trelleborg Sealing Solutions

Chemical compatibility charts are often used as a quick and concise way to match the proper fluid with a seal. However, there is much more to consider with the chemical compatibility of a seal in relation to the fluids in a system.  This information is critical to gaining a reliable and long-lasting seal — and the selection process can be daunting. 

Langzeitverschleißverhalten von Stangendichtungen - Jahrbuch 2022 - Dichten. Kleben. Polymer.

Ein Trend in der Industrie ist es, Lebensdauervorhersagen zu treffen, um z.B. Serviceintervalle festlegen zu können. In Bezug auf Hydraulikzylinder ist die Dichtung ein relevantes Bauteil, für das eine Lebensdauervorhersage aufgrund der Vielfalt der Einflussfaktoren nur sehr schwer abschätzbar ist. In dynamischen Simulationen können theoretisch Verschleiß- und Leckageverhalten durch Festlegung vieler Randparameter im Ansatz abgeschätzt werden. Allerdings sind die Ergebnisse noch nicht ausreichend genau, um zuverlässige Aussagen treffen zu können.

Composite Simulation Grows MORE ROBUST

By Kenneth Wong

The transition from metal to composite is one of the most recent significant changes in manufacturing.
The former material is isotropic, exhibiting uniform stretching and bending behavior in all directions. By contrast,composites are anisotropic. They stretch, bend and break differently in different directions, based on how the fibers are woven together and how the laminates are bonded. This fundamental difference throws many traditional simulation protocols and practices into chaos.

Reduce Vibration and Avoid Stiction in Seals

By Holger Jordan, fluid power segment manager, Trelleborg Sealing Solutions

Stick-slip is not always a big issue, but sometimes it can significantly degrade performance. Potentially, it can cause damage, such as cracks in steel work and strength loss, and even health problems for operators. We look at solutions to combat stick-slip to lower vibration as well as to create damping solutions.
