Abstract

A sealing device is provided for sealing a space between a hub and a spindle pivotally connected by a bearing, the hub being coaxially mounted on the spindle and extending in an axial direction and the bearing having an inner ring. The sealing device includes a radial shaft seal including a shell portion having an outer static sealing surface disposeable against the hub and a hinge portion having a radial sealing lip. A sleeve member includes an inner static sealing surface disposeable against the spindle, a running surface contactable by the sealing lip and a sleeve portion. The sleeve portion extends in the axial direction beyond a side surface of the bearing inner ring and is disposeable about a shoulder diameter of the bearing inner ring.
