An elastomeric seal assembly for use with a bearing cup mounted on a trunnion of a universal joint cross member includes an elastomeric seal attached to a metallic support ring. The metallic rings are pressed into the open ends of the bearing cups and are retained therein by friction. The elastomeric seals each include first, second and third radially inwardly extending sealing lips. When the bearing cups and sealing assemblies are mounted about the trunnions the annular lubricant sealing lip engages the frustoconical sealing surface of the trunnion. The annular lubricant sealing lip is slanted towards the closed end of the cup to prevent lubricant from flowing past the seal and out of the roller bearing region. The second sealing lip engages the cylindrical sealing surface of the trunnion and is slanted towards the open end of the cup to resist the entry of abrasive contaminants into the roller bearing region. A third sealing lip engages the cylindrical sealing surface of the trunnion and is slanted in the same direction as the first contaminant sealing lip. The second contaminant sealing lip resists the movement of contaminants towards the first contaminant sealing lip thereby prolonging the life of the seal and universal joint.
