A railway locomotive truck provides improved mountings and/or configurations for traction motor axle support bearings to improve their wear life. These include tilting, or sloping, of the support bearing bores to more closely match the orientations of the bearing journal surfaces on the axles which slope as a result of bending of the axles under the weight of the locomotive. An added feature is forming the bearing bores with a slight conicity to accommodate slight tilting of the traction motor under heavy loads due to taking up of the clearances in the motor support axle bearings. Other features include various ways of mountings or altering the construction of the axle bearings to provide the desired positioning.
