A roller bearing with cage fasteners that prevent cage separation under adverse operating conditions. The roller bearing has an inner race, outer race, a plurality of rollers, a roller cage, and cage fasteners. The inner race is disposed about a rotational axis and includes a peripheral surface facing the rotational axis with an inner nominal diameter of seven inches about the rotational axis. The outer race has a circumferential surface surrounding the inner race and includes an outer nominal diameter of twelve inches about the rotational axis. The roller cage is disposed between the inner race and the outer race and includes a first piece and a second piece connected together by the cage fasteners. Each of the cage fasteners includes a first surface having a first effective area in contiguous engagement with the first piece of the roller cage, and a second surface having a second effective area in contiguous engagement with the second piece of the roller cage. The first and second effective areas are generally equal to each other.
