Axle assembly for a railway or other types of track riding vehicle including a first axle member fixed to a first wheel to ride on one track and extending longitudinally outwardly from the wheel, with a groove adjacent the outermost end of the axle, a second wheel with a longitudinally, outwardly extending axle shaft fixed at one end to the second wheel where the outer end of the second axle shaft includes a generally cylindrical housing having an open to receive the outermost end of the first axle. A first plate is provided to be received on the open end of the housing and has a central aperture, of diameter generally equal to the diameter of the first axle member, so the first axle member extends therethrough and so the end of the first axle and the groove are located within the housing. A first bearing is of diameter generally equal to the inner diameter of the housing located within the housing to receive the outer end of the first axle to support the end of the first axle and a second thrust bearing having a diameter generally equal to the inner diameter of the housing is retained therein to also receive the end of the first axle so that the second bearing is located between the groove and the first plate. A retainer device is provided to be received in the groove within the housing to retain the axle from longitudinal outward movement with respect to the housing.
