ABSTRACT:
Two bearing cups are rigidly mounted on side portions of a rocker arm and extend over respective arms of a bearing support member. Rolling members within an annulus formed between the bearing cups and the bearing support member permit the rocker arm to oscillate rotatably with respect to the bearing support member. Each bearing cup has a stepped bottom surface with a first bottom portion engageable with ends of the rolling members to limit axial movement of the rolling members and a second bottom portion, offset axially with respect to the first bottom portion, engageable with stop surfaces to limit axial movement of the rocker arm with respect to the support member. A bearing assembly for mounting within a rocker arm is also disclosed.
