In 1932, Freudenberg experimented with the first radial shaft seal rings, entering new territory with the concept of offering a complete element consisting of a leather sleeve embedded firmly in a sheet metal casing. Today the Simmerring® is a high-tech product whose key functions have long moved past the sealing of rotating shafts against housings. New materials continue to open up opportunities to meet the needs of specific applications. This has made Simmerring® a unique success story.
In a special web program, Freudenberg Sealing Technologies (FST) is highlighting Freudenberg’s 175th anniversary to draw customers’ attention to this high-tech product as well as FST’s engineering expertise and capacity for innovation.
