Abstract
An extended life conveyor chain in which a wheeled chain member (e.g. a chain link or chain supporting trolley) includes a projecting detent which engages a detent receiver on a load bearing wheel inner member locking the inner member against rotation with respect to the link. A rotating outer wheel rotates around the inner member. This relieves torsional pressure on a swaged connection between the inner non-rotating wheel portion and a fixed axle on the link and prevents resulting wear.
