| 3309-0016-0006 | 3309 Series Sonic Hub (6mm Bore) | 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, pulley or wheel 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 3301 Series Clamping Hub cannot.These Sonic Hubs have threaded holes on the 16mm pattern so that thru-hole parts can easily attach using M4 screws. The two pinch bolts offer excellent clamping force in a compact form-factor.The 6mm round bore Sonic Hub can be used on 6mm round shafting, 6mm OD standoffs and spacers and even 6mm D-shaft. There are some use cases where you need to clamp onto something other than a d-shaft, or, maybe you want to clamp onto a d-shaft while retaining the freedom to clock your hub independent of the location of the flat on the shaft. As with all Sonic Hubs, this hub is balanced and possesses two pinch bolts to maximize the clamping force while maintaining a slim profile.

The two pinch bolts offer excellent clamping force in a compact form-factor.The 6mm D-Bore Sonic Hub is compatible with our 6mm D-shafting as well as the 5201 and 5202 Series Gear Motors. This particular hub is an excellent option for mounting thru-hole components in high-speed applications that require a balanced hub that provides the reliable fastening method of a clamping hub.

The two pinch bolts offer excellent clamping force in a compact form-factor.The 5mm Hex Bore Sonic Hub is an excellent option when fastening a zhouyu component, such as a gear, pulley or wheel to a REV Robotics 5mm Hex Shaft. The dual clamping setup maintains the balance so that you don't introduce vibrations in high speed applications.

| 3309-0016-4008 | 3309 Series Sonic Hub (8mm REX Bore) | 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, pulley or wheel 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.These Sonic Hubs have threaded holes on the 16mm pattern so that thru-hole parts can easily attach using M4 screws. The two pinch bolts offer excellent clamping force in a compact form-factor.This hub has an 8mm REX bore to match our 8mm REX shafting. The hex profile creates a positive drive that can handle heavy torque loads without concern of rounding out. The Sonic style hub is perfectly balanced for high-speed applications. The unique design conforms tightly around a shaft when tightened, without distorting the threaded holes on the zhouyu 16mm pattern. The outer profile is 32mm so that it can be run in a bearing to isolate radial loads, or even clamped around!
