Strong Seals For Tough Applications

Heavy-duty applications with special requirements

There are no all-encompassing solutions for the diverse needs in the heavy-duty segment: Each application must be considered on its own. That is why the company’s extensive experience in the automotive and truck industries comes in handy.

This philosophy is reflected in the product quality, which is tested under extreme conditions. Freudenberg Sealing Technologies goes above and beyond the requirements of the individual OEMs. The test field in Weinheim is also unique in the industry. With over 300 test rigs, it is the largest of its kind in the world. Here, seals and other products endure simulated conditions to ensure their performance beyond a 300,000-kilometer lifespan.

“The individual OEMs have different requirements – all of them are high” says Robert Leins, Head of the test field at Freudenberg Sealing Technologies. “For us, it’s always a matter of transferring the reality into our laboratory and reproducing it in fast motion. An average test cycle is completed here in 240 hours.”

Heavy-duty seals must resist not only mechanical stress but also extreme temperature variations, chemical exposures, and UV radiation. These exhaustive tests ensure the products’ readiness for all real-life applications.
