How many hubs are included?** A: Two hubs as pictured. **Q: Do these function as non-moving bearings to support a long 6mm shaft? How do these work?** A: These are just aluminum machined hubs. The Hub fits on a 6mm shaft and then gets tighten down to that shaft with a set screw. There are threaded holes in the hub so you can attach things to it if you want or need to. There are no bearing. I used mine to attach to a motor with a 6mm shaft then bolted on a piece to the hub that then turned a head on a Halloween prop. Almost like a old time steam train wheel. **Q: Does this work with tetrix parts? also if anyone can answer this is it ftc legal?** A: YES! ## Frequently Bought Together - Pololu 1083 Universal Aluminum MOUNTING HUB for 6mm Shaft Pair, 4-40 Holes - Greartisan DC 12V 1000RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Eccentric Output Shaft 37mm Diameter Gearbox - Black 37mm DC Gear Motors Mounting Bracket, Iron Anti-Rust Gearbox L-Shape Fixed Seat, Gear Reduction Motor Holder --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/294467914-pololu-1083-universal-aluminium-mounting-hub-for-6mm-shaft-pair](https://www.desertcart.us/products/294467914-pololu-1083-universal-aluminium-mounting-hub-for-6mm-shaft-pair) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
