Trelleborg Hydraulic Seals

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

Hydraulic rod seals prevent fluid from leaking out of the cylinder, while hydraulic piston seals prevent fluid from flowing over the cylinder head. This allows pressure to build up on one side of the piston, causing the cylinder to extend or retract. Wear rings guide the piston and connecting rod within the hydraulic cylinder, absorbing transverse forces and preventing metal-to-metal contact. Scrapers or wipers scrape dirt, foreign particles, chips or moisture from the piston rods as they are drawn into the cylinder, preventing contamination.
