## Description

These universal mounting hubs are designed to work with most 6mm shafts, including round and 'D' shafts.

Review: it worked great (as an interface between a small motor shaft and ... - This is a fairly specific item, so I'll assume you have a use in mind for this. For my use, it worked great (as an interface between a small motor shaft and a halloween prop) I'm happy with this purchase, very nice quality.
Review: More effective design - My first purchase was a cheaper hub that had set screws on opposite sides of the central sleeve and no set screw in the flange part of the hub. The problem with this is that the set screws bear all of the force of keeping the hub from spinning on the shaft, and there are precious few threads against which to distribute that force. When I saw this hub with a wider flange that is threaded and on the same side as the second set screw I knew I'd found the right hub. (Short of finding a hub with a D-Shaped hole, anyway.) Since both screws are on the same side both of them positioned on the flat part of the shaft is MUCH stronger than the other approach. The long thread path through the flange also provides lots of surface area for the threads to distribute force against and hold the hub securely. Like I said above, a hub with a D-shaped hole would be best since it would be impossible for the shaft to slip and the set screw's job is merely to keep the hub from falling off. Unfortunately, these are so far impossible to find in the 6mm size I needed. Short of that this hub is the best design I've yet found for high-torque use cases.

## Features

- These universal mounting hubs are designed to work with most 6mm shafts, including round and 'D' shafts.
- Each hub has six mounting holes for 4-40 screws (not included), letting you mount custom wheels or mechanisms to your motors.

## Questions & Answers

**Q: Do you have a print for the bolt hole pattern of this hub (the 6 tapped holes)?**
A: https://www.pololu.com/file/0J161/1083-6mm-4-40-hub-dimensions.pdf

**Q: Picture shows two hubs, but nothing in the description confirms quantity. 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!

### ⭐⭐⭐⭐ Set screw problem
*by T***P on August 3, 2023*

These are beautifully machined. My only complaint is that tightening the set screw using the included wrench tight enough to avoid loosening on the shaft causes the wrench to get stuck in the head of set screw. To get it out you have to reverse the wrench, and that just causes the screw to loosen. You might be able to use regular 4-40 screws, but the ends aren't cupped like a set screw, so they might not hold either. Maybe with loctite?
