A wheel assembly is composed of multiple wheels, each featuring a hub with spokes and a main axle bore, and cross-roller sub-assemblies that include symmetrical axles and solid bushings, as well as peripheral rollers. The cross-roller sub-assemblies are overmolded with the wheel hub to form a peripheral axle ring. A method of assembling the wheel assembly involves creating the cross-roller sub-assemblies by overmolding the solid bushings with peripheral rollers, and then placing these sub-assemblies in a mold to form the peripheral axle ring.
