Awesome Extras

These Pololu universal aluminium mounting hubs allow you to mount custom wheels and mechanisms to 8mm diameter motor shafts

The set includes two hubs, four M3 set screws for securing the hubs to motor shafts, and one 1.5mm Allen wrench for use with the set screws. Each hub has six threaded mounting holes for M3 screws (not included).

We have an assortment of universal mounting hubs available, spanning several shaft sizes and featuring mounting holes threaded for metric or imperial screws. These universal mounting hubs are designed to work with most 8mm diameter shafts, including round shafts and “D” shafts.

Each of the two included hubs has six mounting holes for M3 screws (not included), letting you mount custom wheels or mechanisms to your motors. The four included M3 hex set screws (two for each hub) allow secure coupling of shaft to hub, with the longer set screws intended for the deeper of the two set screw holes. A 1.5mm hex wrench is included for use with the set screws.
