ABSTRACT:
Positive lubricating elements and positive indexing elements are retained between raceways of two relatively rotating race members of a bearing assembly. Sliding load bearing segments may also be retained between the raceways, and the indexing elements derive force from relative rotation of the raceways to index or move the bearing segments relative to both raceways. Lubricant is forced into the raceways by the lubricating elements. Preferably the lubricating and indexing elements are both defined by hollow roller spring elements which are resiliently compressed between the raceways and which separate adjacent bearing segments. Lubricant is carried within the hollow interior of the roller elements. Means associated with the roller elements and race members operatively reduces the volume of the interior of the roller element and forces lubricant on the raceways, preferably at positions where the race members withstand large loads. At other positions the interior volume of the roller element is expanded to accept more lubricant.
