20110227293 | RADIAL SHAFT SEAL ASSEMBLY WITH LUBRICATION RETENTION AND DEBRIS EXCLUSION FEATURE AND METHOD OF CONSTRUCTION THEREOF - A radial shaft seal assembly includes an outer case having an axially extending cylindrical outer rim and an axially extending cylindrical inner rim spaced radially from one another by an annular pocket. A radially extending first leg connects the outer rim to the inner rim and a second leg extends radially inwardly from the inner rim to a free end. The assembly includes a wear sleeve having an axially extending cylindrical wall with an outer surface providing a running surface and a flange extending radially outwardly from the running surface. A seal lip extends inwardly from the free end of the second leg into sealing abutment with the running surface. A first porous filter is received in the pocket, and a second porous filter extends in substantial abutment with the outer rim and the second leg of the outer case. | 09-22-2011 |
20120313329 | Vented Dual Lip Seal And Method Of Making - A method of making a dual lip seal is provided including the steps of molding first and second seals to a respective first and second insert. The first and second seals each include a body portion molded to the first and second inserts and including a seal lip extending from the body portion. The body portion of the first and second seals includes a side surface including at least one projection and at least one recess. The at least one projection and the at least one recess of the first and second seals are aligned so that the at least one recess of the first and second seals each receive a corresponding one of the at least one projection of the other of the first and second seals. A heating process is then applied to the first and second seals to bond the seals together via vulcanization. | 12-13-2012 |
20150008647 | SEALING ASSEMBLY ADAPTED TO BE INSERTED BETWEEN TWO RELATIVELY SLIDABLE MEMBERS - A sealing assembly insertable between a rod and a guiding bush of a shock absorber to form a sealing and guiding unit for the rod is provided. The assembly includes an elastomeric ring having a first and a second annular lip which extend axially and radially overhanging; and a reinforcing ring integrally coupled to the elastomeric ring, radially on the side of the first and of the second sealing lip. The reinforcing ring is integrally coupled in one piece with the elastomeric ring, on the exterior of the elastomeric ring and on the side of a lateral surface thereof facing towards the lips, the reinforcing ring coupling in sliding manner with the rod to serve as guide therefor. The sealing ring coupling by interference with the guiding bush. | 01-08-2015 |
