FULL-FACE VS. A-PLATE DRUM SPROCKETS
FULL-FACE DRUM SPROCKET
Increased surface area resulting in lower contact pressure between the sprocket and chain, along with greater wearability, make full face the standard for most applications.
A-PLATE DRUM SPROCKETS
A-Plate style can handle greater misalignment and provide bulk material pass-through; however, less contact area may result in lower life.
OPTIONAL STYLE WITH FLANGE Flanges are different than an
extended shroud even though they can both service the same purpose. A flange is a separate piece that is welded to a plate.
