Abstract

In a rolling bearing for longitudinal movement with respect to a shaft, the rolling elements have longitudinal cross sections with concave central sections adapted to engage a cylindrical machine element, and shaped ends adapted to roll on a support surface of the machine element. The bearing includes a shell structure for guiding the rolling elements to follow continuous pathways. Each pair of adjacent rolling elements are separated from contact with one another by a separating roller having a convex longitudinal cross section which engages the concave portions of the rolling elements with line contact.
