Corrosion-resistant trolley wheel

Abstract

A trolley wheel for use in a conveyor system, the trolley wheel comprising a central shaft, a wheel body, first and second rows of ball bearings, and an inner race. The wheel body and the inner race both comprise a polymer in combination with the trolley wheel being devoid of a metal inner race and being devoid of a metal outer race. The wheel body defines a central rim with opposed first and second sides that respectively define first and second outwardly-angled outer race tracks. The inner race defines first and second inwardly-angled inner race tracks, such that the first row of ball bearings is configured to roll between the first inwardly-angled inner race track and the first outwardly-angled outer race track, and the second row of ball bearings is configured to roll between the second inwardly-angled inner race track and the second outwardly-angled outer race track.
