Abstract
A belt conveyor conveys discrete articles. The belt conveyor includes: a conveyor frame having a top side, a bottom side, and a length extending in the conveying direction for the discrete articles; a conveying belt configured to revolve around the conveyor frame during operation of the belt conveyor; and a belt-guide mounted to the bottom side of the conveyor frame between the conveyor frame and the conveying belt. The belt-guide includes at least two rolling-element bearings. The inner races of the rolling-element bearings are respectively mounted on axles. The axles are parallel to each other and stationary relative to the conveyor frame. The outer races of the rolling-element bearings have direct contact with the conveying belt.
