Rotary seals are used to seal rotating axles and shafts against media from inside or against contaminants from outside. Typical areas of application are drive technology, gearbox construction, electric motors, pumps, agricultural and construction machinery, and the wind power industry. The selection of the correct design depends on the application and the prevailing operating conditions (media, temperature, circumferential speed of the shaft and pressure). Standard designs are offered with an elastomeric or metallic outer sheath. Many designs are also available with a protective lip that additionally seals against dirt from the outside.
