Usage:
Use #10-24x3/4 thread forming screws to attach sprockets or hubs to this wheel. Three (3) screws are sufficient for each wheel.

With Axle and Hub:

If you wish to drive this wheel with an Axle and Hub, you can pick your hub by fitting any of the AndyMark hubs (except the Small DD Globe Hub) to this wheel. Hubs are NOT included in the price of the wheel. If this is your choice, then no bearing is needed. To install a hub onto a 6" FIRST Wheel, use #10-24x3/4 thread forming screws.

If you wish to drive this wheel with a sprocket, then the sprocket needs to be attached to the side of the wheel, and one ball bearing needs to be pressed into the wheel (on one side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0029. For a 3/8" id, use am-0209. Use #10-24x3/4 thread forming screws

With Bearings:

To press bearings into this wheel (for a free spinning wheel or for use with a sprocket), two ball bearings need to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0029. For a 3/8" id, use am-0209.

Good wheels for the price	December 16, 2015
Reviewer: Brian Parrott from Edmonds, WA United States

The wheels are good enough for indoor robots or light weight outdoor robots. I'm not sure how disable they'll be in the sun, but we're happy enough with them to have ordered a second batch!
