Patent number: 11913494Abstract: A hub bearing assembly includes a housing with a vertical bore, a bearing outer ring disposed within the bore and coupled with the housing and a bearing inner ring disposed within the bearing outer ring and having a central bore configured to receive a portion of the shaft. A set of rolling elements are disposed between the bearing outer and inner rings. An upper seal is disposed within the housing bore externally of the outer ring and includes an annular elastomeric seal body and a garter spring biasing a seal lip radially inwardly. A lower seal is disposed between the bearing outer and inner rings. Either the bearing inner ring is sized such that upper seal is disposed about the bearing inner ring or the hub bearing assembly further comprises an annular spacer disposed within the upper seal and adjacent to the upper axial end of the bearing inner ring.Type: GrantFiled: May 9, 2022Date of Patent: February 27, 2024Assignees: PEER BEARING COMPANY, AKTIEBOLAGET SKFInventors: Jordan Eric Gutowski, Andrew Michael Bauer, Stefano Urso, Marco Erminio Panchetti, Massimo Marivo, Giacomo Alvisi, Pierangelo Cherio, Roberto Viglietti, Riccardo Venturucci

Patent number: 9157475Abstract: A contamination-resistant bearing assembly includes an outer ring mounted within a housing and an inner ring rotatably supported from the outer ring. Inboard and outboard seal structures are disposed within a bearing space defined between the rings and prevent contaminants from entering a rolling element lubrication zone. A surface seal may also be included to protect the spherical interface between the housing and outer ring. The improved structure allows dynamic alignment of the bearing assembly when acted on by outside forces and also allows for extended operation under maintenance free conditions with no need for relubrication.Type: GrantFiled: July 8, 2010Date of Patent: October 13, 2015Assignee: Peer Bearing CompanyInventors: Jordan Eric Gutowski, Stefano Urso, Victor Manuel Marban, Joaquin Gutierrez, Louis John Lenick, Xinying Fan, Brian Alan Cohen, Daniel Nicholas Mazzarella, Feng Zhao

Patent number: 8328428Abstract: A hub-bearing assembly serves to rotatably mount a soil-working disc (D) on a supporting axle (A) of an agricultural machine. The assembly comprises a hub-bearing unit (10) and a sealing device (20). The a hub-bearing unit has a radially outer, rotatable outer race (11) from one side of which a flange (12) radially extends for mounting a disc (D). The sealing device (20) is mounted on a side of the hub-bearing unit opposite to the side of the flange (12). The radially outer surface of the assembly has a portion (38) intermediate the flange (12) and the side of the sealing device (20), which is radially recessed so as to serve as a preferential seat for winding wires picked up from the fields during use of the agricultural machine.Type: GrantFiled: May 24, 2007Date of Patent: December 11, 2012Assignee: Aktiebolaget SKFInventors: Ove L. Andersson, Lorenzo Dellamore, Gianmario Fadda, Maurizio Giovannelli, Mauro Sassi, Stefano Urso, Wolfgang Husslein, Cristian Concu
