Abstract
A drive chain has opposed pairs of inner link plated that are interconnected by cast outer links. Pins pass through aligned apertures in overlapping end portions of the inner and outer links. Each pin is fixed relative to the inner link. The outer link has open or blind bores that receive end portions of the pins in a pivotal relationship. A bearing area is defined between the outer surface of the pin and an inner surface of the outer link bore. The provision of a bearing area in the outer link makes maintenance and sealing easier.
