ABSTRACT:
A roller bearing assembly having an outer case (1) which contains an elastically yieldable sleeve 2 in which is enclosed a thin elastically yieldable ring 3 whose inner surface acts as a raceway for rollers or needles (6) carried by the cage (7). The elastic ring has a plurality of angularly spaced apart regions discontinuities (4a, 4b) defining pre-stressed regions adapted to ensure, by a radial deformation, a localized gripping of the rollers or needles under the action of the sleeve when the roller bearing assembly is mounted on a shaft (8). The outer case (1), the sleeve (2), the roller bearing ring (3) and the cage (7) have an openable structure which permit their spreading being apart to an open for ensuring the mounting of the roller bearing assembly by a lateral engagement of its component parts on the shaft without ends of insertion thereon from either each of the shaft.
