As the demand for air travel continues to rise, so does Trelleborg’s quest to identify solutions that make aircraft and terminal equipment safer, lighter and more energy efficient.

The wide range of sealing products offered by Trelleborg Sealing Solutions can usually satisfy even the most demanding of application requirements. In some cases, though, a custom-designed component is the best sealing solution.

Hydraulic applications are challenging for Seals. Not only must the hydraulic seals prevent leakage of fluid from the Cylinder, but hydraulic seals must also withstand high pressures, extreme temperatures and transverse forces within the cylinder. In such applications, the function of Hydraulic Seals goes far beyond preventing fluid leakage.

Oil Seals, also known as radial oil seals, radial shaft seals or rotary shaft lip seals, are round sealing devices used to seal between two machine parts that rotate relative to each other. They are used to seal lubrication in and/or contamination out, or to separate dissimilar media.

Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing. They are internal to the cylinder head and seal against the cylinder bore, preventing fluid from flowing across the cylinder head. This allows pressure build up on one side of the piston, making the cylinder extend or retract.

Rod seals are used in hydraulic cylinders for fluid sealing. They are external to the cylinder head and seal against the cylinder’s rod, preventing leakage of fluid from within the cylinder to the outside.

Scrapers or Wipers are installed in the sealing configurations of hydraulic cylinders to scrape dirt, foreign particles, chips or moisture from the piston rods as they retract into the system. A hydraulic wiper or scraper prevents contamination of the hydraulic medium that could damage wear rings, seals and other components.
