Abstract
A split roller 150 may be removed from an axle 104 without requiring access to the axle end. A split wheel hub 152 supports a plurality of peripheral rollers 180, which may be arranged in two rows spaced along the hub axis. In a preferred embodiment, the wheel hub comprises two asymmetric hub halves 134, 136 which are fastened together around an axle. Each roller in the second row may be spaced circumferentially between a pair of rollers in the first row. According to the method of the invention, the hub halves are assembled, preferably with some rollers in each of the first and second rows already mounted thereon. Other rollers in each row are then mounted to the assembled hub halves.
