As simplified construction for a conveyor wheel wherein the outer shell of the wheel is formed from two identical shell members which can be identical stampings, with these stampings being hardened and then fixed together to define the assembled shell. The stampings when fixed together are disposed in opposed relationship, and the stampings have inner arcuate raceways which directly define an outer raceway for an annular array of bearing balls. The stampings have outer transversely oriented channel parts which, when the raceways are fixed together, have the open channel parts aligned and abutted to define a generally closed tubular cross section which defines the rim of the wheel. The channel parts have outer flanges which effectively abut and define the outer annular tread of the wheel, the latter being substantially cylindrical to provide a smooth and flat cylindrical surface having a substantial contact area for a load. The edges of the tread are rounded to prevent load damage or hang-up.
