Trelleborg Qualifies A350 Main Landing Gear on World's Most Powerful Test Bench for Hydraulic Seals

The sealing system has successfully passed 20,000 full landing cycles plus additional tests for ice scraping and water spray. To support its customers in proving seals for critical applications, Trelleborg Sealing Solutions invested in the world’s most powerful test bench for hydraulic rod seals. This unique facility allows testing to be carried out that has previously never been possible and has been utilized to qualify the seals for the landing gear of the Airbus A350. The sealing system has successfully passed 20,000 full landing cycles plus additional tests for ice scraping and water spray.

Installed in a specially constructed well, the 18 ton, 260 kW floating-mount rod seal test bench is located at Trelleborg’s research and development center in Stuttgart, Germany. It is capable of simulating, as realistically as possible, the patterns of movements and stresses faced by hydraulic rod seals in some of the most demanding rod seal applications.
