1309 Series Sonic Hub (8mm REX™ Bore)

SKU: 1309-0016-4008

$7.99

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 goBILDA 16mm pattern. The outer profile is 32mm so that it can be run in a bearing to isolate radial loads, or even clamped around!

Features

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.

Precisely Machined
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.
