ABSTRACT:
Two support arms of a bearing support member extend in opposite directions, each support arm having an overlying bearing cup engageable with the rocker arm. Rolling members within an annulus formed between the bearing support member and the bearing cups provide free rotary oscillation of the rocker arm with respect to the bearing support member. At least one support arm has a crowned surface such that radial load is distributed along the length of the rolling members when misalignment of elements of the rocker arm assembly occurs. A bearing assembly for mounting within a rocker arm is also disclosed.
