A conveyor system (30) comprises: a boat (20), a feed belt (36), a feed pulley (38), and improved railings (34). The boat (20) is adapted to carry a component or components, such as semiconductor chips (32), therein. The feed belt (36) is driven by the feed pulley (38). The feed belt (36) is adapted to move the boat (20) along the conveyor system (30). The improved railings (34) are adapted to retain the boat (20) and to define a path for the boat (20). A set of bearings (44) are coupled to each of the improved railings (34) in locations such that the boat (20) will contact the bearings (44) rather than the railings (34) for at least part of the path as the boat (20) moves along the conveyor system (30).
