Abstract

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.
