This 3/8” hex bore Hyper Hub is a beefy solution for fastening a component to a 3/8” hex profile shaft—such as AndyMark Robits Hex Shafts as well as VEX 3/8” Hex and ThunderHex Shafts.
Two pinch bolts constrict the hub onto the shaft for a no-slip connection between the shaft and the hub. A built-in shim provides for contact with a bearing without binding against the bearing’s outer race. And like all Hyper Hubs, this hub is balanced for use in high-speed applications!
Made for 3/8" Hex Shafting
This hub allows you to mount components to a 3/8" hex profile shaft, including AndyMark Robits Hex Shafts as well as VEX 3/8” Hex and ThunderHex shafts.
Part of a Large Ecosystem of Parts
The 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 Balanced
The innovative Hyper Hub design is perfectly balanced. It will not introduce vibrations into your build, even in high-speed applications.
The generous amount of shaft contact—paired with the positive drive provided by the hex profile—allows this hub to be used in high-torque applications.
Will Not Get Stuck or Marr Shaft
Our 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.
This hub is machined for high-precision fitment.
Will Not Corrode or Rust
The body of this hub is aluminum, and the pinch bolts are zinc-plated steel.
Lightweight & Strong
Aluminum has an excellent strength-to-weight ratio, allowing this hub to be both light and strong.
