This wheel is designed to be supported by 1.125 in. OD (FR8) flanged bearings, and driven by motion hardware that utilizes a 1.875 in. 6-hole bolt circle found in many AndyMark and competition robotics products. To mount one of these to the rear of the wheel use a 250 Sprocket and Pulley Spacer. To mount one to the front, use a 550 Sprocket Spacer. This wheel does not include tread material, which is available separately to tailor this wheel's performance to your application.
Note: This wheel is designed to utilize rivets to attach the tread to the wheel. AndyMark recommends steel 1/8" diameter rivets with a 0.251" - 0.312" grip range. The wheel has been manufactured with no holes on the rim, as it is intended to be a blank canvas for teams to install rivets freely.
