A bearing assembly may include an inner ring, an outer ring, and a plurality of rolling elements supported therebetween. An annular seal may be disposed between the inner and outer rings, the seal including a metal portion having a mating surface configured to contact a wall of the inner ring. A bead seal may be secured to the mating surface and may extend around a circumference of the seal, the bead seal contacting and forming a seal between the mating surface and the wall of the inner ring. The bead seal may be secured to/within a groove formed in the mating surface. The bead seal may be over-molded on the groove.
