    Abstract: The steering bearing assembly includes a bearing assembly with an upper race that has a circular inner periphery and a tubular protrusion that extends axially from the inner periphery. The tubular protrusion is provided with a plurality of axial splits and an externally threaded wall which tapers gradually toward a free end thereof. A positioning seat with an internally threaded wall that complements the external wall of the tubular protrusion is mounted around the latter and above the upper race in such a manner that the free end of the tubular protrusion extends beyond the uppermost portion of the positioning seat. The tubular protrusion retracts radially and inwardly upon tightening of the positioning seat.
