ABSTRACT:
A roller bearing assembly is provided which is adapted to enhance lubrication performance for preventing seizure and for reducing frictional torque during rotation. The roller bearing assembly includes an inner ring (1), an outer ring (2) and a roller (3) rollably interposed between these inner and outer rings. The inner ring (1) is formed with a rib (4) making contact with a greater end face (7) of the roller (3) for guiding the rolling motion of the roller (3). A recess (5) is formed centrally of the greater end face (7) of the roller (3). A stopper member (6) for preventing oil invasion is fitted in the recess (5) of the roller (3).
