This 8mm REX Bore Sonic Hub has thru-holes on the 16mm goBILDA hub pattern. Thru-hole hubs allow you to fasten to parts that have threaded holes. Having thru-hole hubs on hand will change the way you look at using a hub - fasten it to another hub to create a coupler; sandwich a part between a threaded hub and a thru-hole hub for an extreme hold, or attach it to the end of a goRAIL or goTUBE to drive the extrusion for a collection mechanism!
Made for 8mm REX Shafting
This hub allows you to mount components to an 8mm 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 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 Sonic Hub design is perfectly balanced. It will not introduce vibrations into your build, even in high-speed applications.
Will Not Get Stuck or Marr Shaft
Our patented Sonic Hub design 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.
