## Description

The 6mm D-Bore Double Sonic Hub is compatible with our 6mm D-shafting as well as the 5202 Series Gear Motors. The 16mm width of the hub provides additional clamping force and surface area when compared to the 1309 Series Sonic Hubs. Furthermore, it provides additional thread depth to hold components on each side of the hub if needed.

### Features

**Made for 6mm D-Shafting** This hub allows you to mount components to a [6mm D-shaft](https://www.gobilda.com/stainless-steel-d-shafting-6mm-diameter/).

**Part of a Large Ecosystem of Parts**
The goBILDA® ecosystem has many parts that bolt directly to this hub. That includes [wheels](https://www.gobilda.com/wheels-tires/), [gears](https://www.gobilda.com/hub-mount-gears/), [sprockets](https://www.gobilda.com/sprockets-chain/), [track sprockets](https://www.gobilda.com/tracks/), [timing pulleys](https://www.gobilda.com/timing-belts-pulleys/), [round belt pulleys](https://www.gobilda.com/round-belts-pulleys/), [winch pulleys](https://www.gobilda.com/cable-pulleys/), [control arms](https://www.gobilda.com/push-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](https://www.gobilda.com/sonic-hubs/) 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.
