Bearing seal with oil deflectors

In combination with an anti-friction bearing assembly including coaxial inner and outer relatively rotating bearing components defining a sealed lubricant-containing cavity therebetween, a radial sealing assembly for sealing the cavity, the sealing assembly including a rigid support ring having a generally cylindrical body portion adapted to fit within and form a lubricant-tight seal with a radially inwardly directed cylindrical bore in the outer bearing component and a resilient ring-shaped sealing body mounted on the support ring in position to form a lubricant seal with a radially outwardly directed cylindrical surface coaxial with and relatively rotating with respect to said cylindrical bore, the sealing body including a dust sealing lip adapted to contact and form a dust seal with said radially outwardly directed cylindrical surface and a primary sealing lip forming a lubricant seal with said radially outwardly directed cylindrical surface, said primary sealing lip comprising,

• a generally frustoconical surface directly facing the sealed lubricant-containing cavity,
• a plurality of generally wedge-shaped oil deflectors integrally formed on and projecting from said generally frustoconical surface into said sealed lubricant-containing cavity, said oil deflectors being arranged in an annular ring around said primary sealing lip, each said deflector being defined by a first surface extending in radially outwardly spaced generally opposed relation to said radially outwardly directed cylindrical surface and intersecting said generally frustoconical surface along a first line, and an oil deflecting surface intersecting said first surface and said generally frustoconical surface,
• each said oil deflecting surface including a leading and a trailing surface portion each inclined axially relative to the direction of relative rotation of said inner and outer bearing components from an apex spaced axially from said first line to a point of intersection with said first line.
