A drill bit includes a bit body having one or more blades extending therefrom and a plurality of cutters secured to the one or more blades. One or more rolling elements are positioned on the bit body, and each rolling element has a rotational axis and provides one or more cylindrical bearing portions rotatable about the rotational axis. Each rolling element is rotatably coupled to the bit body within a housing that defines one or more internal bearing surfaces that partially enclose the one or more cylindrical bearing portions but leaves a full length of the rolling element exposed.
