A bearing assembly includes an inner race and an outer race, with the outer race positioned such that the inner race is an opposed and spaced apart relation from the outer race. Roller elements are disposed between the inner race and the outer race. A resilient seal element extends adjacent to a flange element, maintaining an effective seal during axial and/or radial movement, such as that caused by thermal expansion, of the resilient seal element relative to the flange element. The resilient seal element excludes contaminants from entering the bearing assembly and retains grease or lubricant within the bearing assembly.

L'invention concerne un roulement qui comprend un chemin de roulement interne et un chemin de roulement externe, le chemin de roulement externe étant placé de telle manière que le chemin de roulement interne se trouve opposé et écarté par rapport au chemin de roulement externe. Des éléments galets sont disposés entre le chemin de roulement interne et le chemin de roulement externe. Un élément d'étanchéité élastique s'étend adjacent à un élément joue, et maintient une étanchéité efficace au cours du mouvement axial et/ou radial, tel que celui qui est entraîné par l'expansion thermique, de l'élément d'étanchéité élastique par rapport à l'élément joue. L'élément d'étanchéité élastique empêche les contaminants de pénétrer dans le roulement et confine la graisse ou le lubrifiant à l'intérieur du roulement.
