The inner sealing ring (10) is set in the bore of the socket. The outer ring (12) set on a pin define the collecting chamber (21) for water and dirt. The sealing lip (19) of the inner ring is pref. mounted on an arm (22) which reaches practically up to the outer sealing ring (12) and this arm, together with the remaining sealing body (13) of the inner ring, form a V-shaped channel (23) which serves to drain off the dirty water. USE/ADVANTAGE - When the bearing is stationary, no water passes into it, so that the lubrication effect of the bearing does not change and the service life is increased without the need for maintenance.
