Sprockets for Harsh Environment Flat-Edge Roller Chain
The teeth on these sprockets are sized to fit Harsh Environment Flat-Edge Roller Chain. To avoid interfering with material conveyed on your chain, the teeth are short and won’t stick out above the chain. For a custom fit on your shaft, machine these sprockets to your exact specifications. They come machined to the shaft diameter listed and are machinable up to the maximum shaft diameter size.

Hub-Mount Screw-Clamp Bushings
Transfer torque directly from a shaft to a hub. These bushings install over your hub to mount a sprocket, pulley, or gear to a shaft at the same time. Common in industrial gearbox applications, they can also connect a hollow shaft over a solid shaft. As screw-clamp bushings, they're good for shock loads. When you tighten the included clamping screws, the outer rings compress against a sprocket, pulley, or gear in between them, causing the inner rings to tighten around the shaft.
