Abstract

The annular cage 12 comprises, on the one hand, a ring exhibiting a plurality of cells 14 designed to receive and to hold balls and, on the other hand, a projecting annular portion 20 which exhibits a deep annular groove 21 extending from the end edge 22 of the projecting portion 20 and over the most part of the said projecting portion. The said groove 21 is formed substantially in the median part of the projecting portion 20, so as to define two flexible sealing lips 23, 24 pointing towards the outside of the bearing. <IMAGE>
