Abstract
A bearing assembly includes a bearing housing; a rotatable shaft extending through the bearing housing; a bearing having an outer race and an inner race with a bearing seal therebetween, the outer race operably coupled to the bearing housing and the inner race operably coupled to the rotatable shaft; and a slinger operably coupled to an outside edge defining the inner race and rotatable therewith while an external periphery defining the slinger is disposed within a groove configured in the housing, wherein the slinger protects the bearing from contamination from the elements while freely spinning absent contact with the housing, the outer race, and the bearing seal.
