The bore Hyper Hub is a heavy-duty, balanced, clamping solution to fastening onto a shaft. The dual pinch-bolts put a mega-hold on the shaft and the extended length of the hub offers excellent surface contact with the shaft. The REX® profile matches a REX shaft so that a positive drive is created and there’s essentially no chance of slipping. As with all Hyper Hubs, this hub is balanced so that it can be used in high-speed applications without introducing vibrations. In addition to the standard threaded holes on the 16mm square pattern, the 1313 Series of Hyper Hubs also has shouldered arms which provide four additional holes on the 32mm square pattern. This provides even more support for those larger builds. The shoulders have a 32mm diameter allowing the hub to nestle into parts which have a 32mm hole for a compact, low moment-arm setup Downloads Variant STEP File Other Files 1 - 8mm REX™ STEP File — 2 - 12mm REX™ STEP File — Features Made for REX® ShaftingThis hub allows you to mount components to an REX® shaft. A "REX®" shaft is part Round and part Hex. An 8mm REX® shaft is 7mm flat-to-flat, like 7mm hex shafts. The difference is, that the tips are precision ground to an 8mm diameter allowing it to fit in an 8mm bearing. The bore of this hub has enough clearance in the corners to accept most 7mm hex shafts. Part of a Large Ecosystem of PartsThe goBILDA® ecosystem has many parts that bolt directly to this hub. That includes wheels, gears, sprockets, track sprockets, timing pulleys, round belt pulleys, winch pulleys, control arms, and more! High-Speed Design - Completely BalancedThe innovative Hyper Hub design is perfectly balanced. It will not introduce vibrations into your build, even in high-speed applications. High-Torque DesignThe generous amount of shaft contact paired with the positive drive provided by the REX™ profile allows this hub to be used in high-torque applications. Will Not Get Stuck or Marr ShaftOur Hyper Hub design (patents pending) holds incredibly tight to the shaft without damaging it. When it is time to disassemble, it readily releases its grip on the shaft. Precisely MachinedThis hub is machined for high-precision fitment. Will Not Corrode or RustThe body of this hub is aluminum, and the pinch bolts are zinc-plated steel. Lightweight & StrongAluminum has an excellent strength-to-weight ratio, allowing this hub to be both light and strong.
