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.

SINGLE, DOUBLE, TRIPLE CONSTRUCTION

SINGLE DRUM SPROCKET Teeth engage with the chain and provide positive traction. The Can is the main structural member of a drum assembly. Optionally a drum assembly may be supplied with no teeth to create a Traction Wheel or Idler.

DOUBLE DRUM SPROCKET To provide structural rigidity and strength, multiple-strand drums are supplied with a Shroud. Optionally multiple-strand drums may be supplied without a Shroud at customer request.

TRIPLE STRAND, COMBINATION SPROCKET & TRACTION WHEEL On triple drum assemblies and greater, Support Plates are installed to provide additional structural strength.
