Publication number: 20040169338Abstract: A sealing ring wherein both the first and the second sealing lip are well protected from mechanical damage/destruction. The relatively more sensitive first sealing lip is particularly well protected and, in particular, is protected from exposure to service life-reducing contaminants. Furthermore, the production of the sealing lip is simple and economical.Type: ApplicationFiled: January 13, 2004Publication date: September 2, 2004Inventors: Gunter Hintenlang, Szaboles Sebok, Jean Philippe Marchal

Patent number: 6474653Abstract: A seal arrangement for a shaft having a broad rpm range, supported in a housing, in particular for axle drives. A radial shaft seal, arranged in the housing bore hole, seals the shaft bearing space from loss of lubricant. A baffle plate, joined to the shaft, and having a lip seal, is aligned radially to the inside, which under the effect of centrifugal force lifts off from its sealing surface at higher rotational speeds of the shaft.Type: GrantFiled: May 5, 2000Date of Patent: November 5, 2002Assignee: Firma Carl FreudenbergInventors: Günter Hintenlang, Uwe Henrich

Patent number: 6062571Abstract: A radial shaft sealing ring has at least one dynamically stressed first seal and at least one statically stressed second seal. The first and second seals are connected to a support ring having a centering seat that is placeable into a housing bore. The support ring has an axial projection which at least partially covers the second seal so as to limit its elastic deformation, and may further contact a housing to be sealed.Type: GrantFiled: January 9, 1998Date of Patent: May 16, 2000Assignee: Firma Carl FreudenbergInventor: Gunter Hintenlang
