Abstract: A roller I-shaft includes an inner shaft, a hollow outer member, and a plurality of bearings. The inner shaft extends along an axis, and includes an outward face defining a plurality of first and second grooves that both extend axially and are alternately spaced circumferentially from one-another. The outer member is disposed radially outward from the inner shaft and includes an inward surface defining a plurality of first channels substantially aligned with the plurality of first grooves, and a plurality of second channels substantially aligned with the plurality of second grooves. The first grooves and the first channels form a plurality of first bearing races, and the second grooves and the second channels form a plurality of second bearing races. The plurality of bearings are disposed in a selected plurality of bearing races comprising one of the plurality of first bearing races and the plurality of second bearing races.
