Product Overview

This is the 8 in. SmoothGrip wheel. In 2010, the Gray 80A Durometer version was provided in the FRC Kit of Parts under the name "FIRST Wheel". No bearings are included.

New for 2021, you can now select a Blue 50A Durometer for maximum traction, or a Black 60A Durometer option.

Usage 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 to this wheel. Hubs are not included with this wheel. If this is your choice, then no bearing is needed. To install a hub onto this wheel, use #10-24x3/4 thread forming screws.

Usage With Sprockets and Bearings:

  • If you wish to drive this wheel with a sprocket, then the sprocket needs to be attached to the side of the wheel with #10-24x3/4 thread forming screws. You will also need to press ball bearings into the wheel so that it may spin on a shaft or bolt. The ball bearings must have a 1.125 in. od. For a 1/2 in. shafts, use am-0181. For a 3/8 in. shafts use am-0209.

    Very easy to adapt to existing frame.

    Good wheels for the price

    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!

    "Dimensions????"

    "I need to know the outside diameter of the inner ring of various bearings. The information will help in design of spacers on shafts. I also need to know the thickness of the hob measured parallel to the spin axis. That's for determining the length of screws that have to pass through the hosed provided for the likes of a sprocket. Where are the CAD or PDF machine drawings? The wheels are fine. It's the data on this web site that bothers me."

    Purchased Rubber Treaded Wheels

    The shipping prices for 2-day and faster deliveries were a bit high. Otherwise, my rating would be excellent.
