BEARING APPARATUS AND METHODS

摘要

An apparatus including a first housing (216) defining an opening and a bearing housing (242) disposed in the opening so that movement of at least a portion of the bearing housing (242) within the first housing (216) and along a first axis (247) is permitted, the bearing housing (242) defining first and second bearing surfaces, the first and second bearing surfaces being spaced apart along a second axis (208) to prevent movement of the bearing housing (242) within the first housing (216) and along the second axis (208), the second axis (208) being perpendicular to the first axis (247).
