DRUM SPROCKET ASSEMBLIES TO KEEP YOUR OPERATION MOVING
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.

SHAFT ASSEMBLY Replacing shrunk fit components can be costly. Complete shaft assemblies reduce installation costs. Split to bolt sprockets reduce future maintenance costs. MOUNTING METHODS: • Finished bore - Slip-Fit & Heat Shrunk • Split-Taper, Taper-Lock & QD Bushing • Split to Bolt • Idler Sprockets (Bearing/Urethane/Bronze/Other) • Keyless locking (e.g. Power-Lock) • Bearing Installation

For ease of installation XTB type bushings are suggested for double hub construction
* Split Taper bushings are standard for single style hubs.
