Patent number: 8851227Abstract: A bearing assembly is for a mechanism including a housing and a rotatable shaft disposed within the housing. The bearing assembly includes a sleeve disposable within the housing and having an inner circumferential surface defining a bore and a radial surface extending radially inwardly from the inner surface. A bearing is disposed within the bore and includes inner and outer races and rolling elements disposed between the races, the inner race being coupleable with the shaft such that the shaft and the inner race rotate as a single unit. Further, a biasing member biases the outer race generally against the sleeve radial surface or a housing radial surface to prevent axial displacement of the outer race during shaft rotation. Preferably, a retainer couples the biasing member with the outer race to retain the bearing and the biasing member within the bore when the assembly is separate from the housing.Type: GrantFiled: January 22, 2010Date of Patent: October 7, 2014Assignee: Aktiebolaget SKFInventors: Christophe Houdayer, Jacques Charpentier, Benoit Arnault, Yves Liverato, Sylvain Bussit, Carole Girardin
