Abstract: A heavy duty wheel-axle assembly for industrial trolley carts in which wheel assemblies are mounted at either end of an axle, an inner bearing race of each wheel positively non-rotationally secured to the axle by interengagement of a non-round shaped position of the axle fitting into a corresponding opening in the race. A hex shape on one end is used to fix one wheel assembly, held by a bolt threaded into a threaded axial bore in the one end of the axle. A pin is inserted into one of a series of axial hub in the hub outside face to engage one side of the bolt hex head. A tee head on the other end of the axle is fit into a recess in the outside face of the other but to establish a non-rotative connection.
