bearing wheels for st charles kitchens corner cabinets

the wheels are approx. 1-1/8 inch outside diameter and two are bolted at the bottom of each half-lazy-susan type shelf (at the 90 and 180-degree positions). the hubs appear to be aluminum. ball bearings ride in the channel between hub and rim.

these cabinets are all-metal and date from sometime after 1952, when wood fronts were introduced by st charles (based on a "care for" sticker still present under the sink, and a celebratory timeline found on the company's website).

remarkably, of 8 wheels (4 shelves, 2 corners), 7 are in fine condition and only 1 has been damaged, some 60 years later.
