0-RW2 RW2 Large Rubber Wheel with Aluminum Hub <p><font color="#00ff66" size="2" face="Arial, Helvetica, sans-serif">These beautifully machined aluminum hubs come with a generously thick rubber
tire for maximum traction.</font></p>
<p><font color="#00FF5A" size="2" face="Arial, Helvetica, sans-serif">The tire mounted on the hub measures in at
31.2mm (1.23in) diameter and overall width (including set-screw flange) of
17mm (0.67in) wide. The hub is drilled for a 3mm axle, but the pilot hole
is 1/16&quot;,
so it's easy for you to drill it out to exactly whatever size you require!
It's a nice, fat, beefy wheel ideal for small robots. Secure it to your motor
shaft with the included 4-40 hex grub/setscrew (requires 0.050 hex wrench).</font></p>
<p><font color="#00FF5A" size="2" face="Arial, Helvetica, sans-serif">The wheel assembly weighs 12 grams.</font></p>
