    8" SmoothGrip Wheel 60a Black

    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.




    • Bolt Pattern: six holes (0.17 in. diameter) on a 1.875 in. diameter bolt circle.

    90 Degree Gusset

    (En stock)

    We are pleased to offer these new gussets that are suitable for 1" based building systems. These thoughtfully designed gussets are made from 1/8" thick 6061-T6 aluminum, which is a much stronger material than other 0.09" 5052 gussets. All of these framing gussets feature a 1" linear hole pattern, with holes suitable for either #10 screws or 3/16" rivets.


    On all of the angle gussets, a generous radius was used on the inside corner for maximum strength. The various angle gussets, along with the quad and tee gusset are used together to create structures and sub-assemblies for your robot. Our bearing and Sport gussets are perfect building blocks to create a massive variety of mechanisms and assemblies to suit your needs.
