Two support arms of a bearing support member extend in opposite directions, each support arm having an overlying bearing cup engageable with a rocker arm. A bearing sleeve is mounted over each support arm between the respective bearing cup and the bearing support member to provide an inner raceway. Each bearing sleeve has sufficient radial clearance with respect to the respective support arm such that the bearing sleeve precesses with oscillation of the rocker arm. Rolling members within an annulus formed between the bearing support member and each bearing cup allow the rocker arm to freely oscillate rotatably with respect to the bearing support member. |
