Belt Tensioning Methods for Small Package Conveyors

As shown in the figure below (Figure A), the tension on the belt is accomplished by turning the screw at the end of a conveyor. This pushes the bearing block towards the end of the conveyor, which adds tension to the belt. There is another, identical jack-screw located on the opposite side of the roller.
