Publication number: 20150184751Abstract: A seal assembly of the present invention is used for sealing a space between a housing and a rotary shaft disposed at least partially within the housing. The seal assembly includes a generally annular sealing member having a central portion and two axially-spaced apart side portions each extending generally radially from the central portion to define a generally annular groove. The assembly includes a generally annular support member disposed within the sealing member groove and configured to retain the central portion disposed generally against the other one of the shaft and the housing. The assembly eliminates problems associated with prior art designs such as static leakage of oil, clogging up the spirals with carbonized oil that negatively impact lifecycle of the fluid seals.Type: ApplicationFiled: December 31, 2013Publication date: July 2, 2015Applicant: AKTIEBOLAGET SKFInventors: Yefim Epshetsky, Alex Paykin, William Schaid, Stellario Barbera

Patent number: 8371757Abstract: A sealing device is to be fitted at a side of a bearing unit in order to seal a gap (15) between a stationary race (11) and a rotatable race (10) of the bearing unit. The device includes a relatively rigid reinforcing insert (16) of disc-annular shape, and a gasket (17) of relatively soft rubber or elastomeric material, over-moulded or vulcanized onto the insert (16). The gasket forms two opposite peripheral sealing portions (18, 19) intended to perform a static sealing action against the rotatable race (10) and a dynamic sealing action on the stationary race (11), respectively. The insert (16) includes magnetized or magnetizable material for forming, at predetermined angular zones or fields, a sequence of alternate and/or spaced north/south poles, in order to act as an encoder.Type: GrantFiled: December 19, 2011Date of Patent: February 12, 2013Assignee: Aktiebolaget SKFInventor: Stellario Barbera
