Our photo this month is the sprocket plugs used on the rollers in our roller conveyor systems. Unlike most other conveyor manufacturers, the rollers that we fabricate here at our Downers Grove facility, feature a one-piece sprocket/shaft end design. This unique design eliminates the use of a bushing to attach the separate sprocket to the end of the roller. The bushing and sprocket design introduce the possibility of the sprocket not being perpendicular to the shaft or creating an out of round condition, leading to misalignments in the conveyor driver system. This misalignment leads to higher maintenance costs, frequent production downtime, and a noisier conveyor line. Our sprocket plugs ensure that the sprocket will be correctly aligned providing years of quiet, trouble-free conveyor systems.
