Sonic Hubs

Sonic Hubs are more balanced than even set screw hubs (and with just as much clearance). Make them your go-to hub for high speed applications leaving behind concerns about marred shafts or lost set screws. The pattern to fasten components to, and the clamping mechanism to hold the hub onto a shaft, are completely isolated from one another.  This means you can tighten the dual pinch bolts to clamp down on a shaft and you haven't distorted the holes you need to use for mounting components to the hub.  Likewise, you can fasten the hub to a gear, sprocket or pulley prior to tightening onto a shaft since the clamping mechanism is able to function regardless of what the hub is connected to.  Since the Sonic Hub clamping mechanism is pulled in toward the center, the hub can fit in recesses and clear where a 1301 Series Clamping Hub cannot.
