The Hyper Hub design is both balanced, and heavy duty. The increased barrel length of the Hyper hub, as compared to a standard clamping hub, provides more shaft-to-bore surface contact for a super tight hold. This length not only increases holding power, but also provides more support to battle heavy radial loads. Similar to a Sonic Hub, a Hyper Hub is able to fit in areas where a standard clamping hub might run into clearance issues while rotating. This 8mm REX bore hyper hub is one beefy solution to fastening a component to an 8mm REX shaft. By nature, since it’s a Hyper Hub, it’s balanced for high speed applications. The internal bore matches that of 8mm REX shafting so that a positive drive is created, but we went ahead and added pinch bolts for a little extra reassurance. The pinch bolts constrict the hub down onto the shaft for a no-slip connection between the shaft and the hub. Due to the added length of the Hyper Hub, when compared to other hub styles, this is the preferred design for handling high torque loads. As with all Hyper Couplers, this coupler is balanced so that it can be used in high-speed applications without introducing vibrations.
