... two bearings. It is a radial bearing load because it is acting in the direction normal to the shaft centerline. Since the helical gear is mounted on the shaft at equal distances from both bearings, ... on the bearing. Since the gear is equally spaced between the two bearings supporting the shaft, each bearing will support half the load, F. Therefore, the radial reaction, W, of each be...
