A bearing race seal for universal joints has an improved coating member which retards intrusion of contaminants, and thus resists corrosion and early failure. The seal includes a metallic backbone with a substantially U-shaped cross-section, and further includes an elastomeric coating member bonded to portions of the backbone. A preferred embodiment of the coating member includes an integral external sealing lip disposed for engagement with a trunnion or similar cross member of a universal joint, and an external body portion disposed for engagement with a journal yoke member. |
