WEINHEIM, Germany, Nov. 8, 2016 /PRNewswire/ -- According to a comprehensive analysis by WITTENSTEIN, a specialist in mechatronics and drive technology, high-performance Simmerrings from Freudenberg Sealing Technologies make a considerable contribution to the reliability of industrial gearboxes. The seals in the investigation are manufactured from a wear-resistant elastomer and are used on the drive and output ends of high-end planetary and angular gearboxes. At these locations, they ensure that no lubricant escapes from the gearbox and that no contamination or product residue can penetrate into it. Over a time frame of more than 10 years, WITTENSTEIN installed more than 1 million high-performance Simmerrings from Freudenberg Sealing Technologies into these gearboxes. With the help of automated evaluation and forecasting software, WITTENSTEIN engineers are analyzing their real-life failure performance. The field data on the seals' reliability clearly show that the number of seal-related malfunctions has declined by a factor of 10 compared to the seals composed of a standard material that was previously used. Since that point, the proportion of malfunctions due to leakage has been just 0.025 percent, and a large share of them can be attributed to premature failures rather than wear. WITTENSTEIN and Freudenberg Sealing Technologies jointly developed the new seals in a close technological partnership. The Simmerrings were manufactured from the elastomer material 75 FKM 170055, which stands out for its high wear resistance. The material especially plays out its advantages with its run-in behavior. That is because seals made of the standard FKM material tend to increase friction and wear under high dynamic stresses and can entrench themselves even in hardened counter-surfaces. This in turn leads to leakage in the event of axial perturbing movements. On the other hand, the robust characteristics of the 75 FKM 170055 materials allow the seal lip's contact pressure to be less and the lip to be narrower, greatly reducing wear.
