8 in. SmoothGrip Wheel, 50A Blue

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.
