ABSTRACT:
A ball bearing fitted with seals mounted on the outer bearing ring and co-operating with sealing surfaces on the inner bearing ring to prevent or restrict entry of fluid into the bearing. The axially outer face of each seal is formed with protrusions spaced at equal intervals around the seal and positioned adjacent its sealing surface, each protrusion having deflecting surfaces arranged to throw or deflect any debris on the sealing surface outwards away from the bearing upon relative rotation between the two members. Each seal comprises an annular disc-like body of resilient material and an annular reinforcing skirt of rigid material, the inner periphery of the body having an annular lip which projects into an annular groove in its sealing surface.
