5mm Pololu universal aluminum mounting hub on a stepper motor with a 5mm-diameter output shaft.
These universal mounting hubs are designed to work with most 5 mm diameter shafts, including round shafts and “D” shafts, such as those on our stepper motors. 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 1.5 mm hex wrench is included for use with the set screws. A dimension diagram of the hub is available under the resources tab.
These hubs will work with most of our stepper motors (the ones with 5 mm shafts), and they also work with 60 mm, 70 mm, 80 mm, and 90 mm Pololu wheels (excluding the Multi-Hub versions; see the individual wheel pages for compatibility details).
Pololu Wheels with 90, 80, 70, and 60 mm diameters in three colors: blue, red, and yellow.
