The runners of the folding rocking chair are fastened to the legs with dowels, which are used to insert the legs into the runners. Folding the chair out and back causes wood-on-wood wear on the dowels. The excessive wear leads to wear on the dowels. iglidur® A200 flange bearings separate the connecting dowels from the chair leg, thus preventing wear. They also act as spacers between the outside of the chair leg and the inside of the runners, thus removing another point of wear.
