Abstract
A rolling bearing assembly (9) comprising an inner ring (10), an outer roller (11) surrounding the inner ring, a needle race (12) placed between the inner ring and the outer roller to allow their relative pivoting about a common longitudinal axis (Z--Z), and an axial retention assembly (13) for retaining the outer roller and the needle race with respect to the inner ring. The retaining assembly comprises at least one split thrust washer (16) which extends radially from a radially outer peripheral region (26) of an axially outer surface of the inner ring towards a retaining groove (24) formed radially inside the outer roller. The split washer comprises an annular central zone (17) for axially retaining the needle race, and at least one series of peripheral supports (18, 19) which are spaced apart and which radially extend the annular central zone.
