These Pololu universal aluminium mounting hubs allow you to mount custom wheels and mechanisms to 3mm diameter motor shafts

The set includes two hubs, two 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 four 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 3mm diameter shafts, including round shafts, “D” shafts, and Tamiya’s 3mm hexagonal shafts.

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

These hubs will work with any mini/15.5D mm metal gearmotor or micro metal gearmotor, and they also work with 60mm, 70mm, 80mm, and 90mm Pololu wheels (excluding the Multi-Hub versions; see the individual wheel pages for compatibility details).
