Pololu Universal Aluminum Mounting Hub for 5mm Shaft, 4-40 Holes (2-Pack)
These universal aluminum mounting hubs allow you to mount custom wheels and mechanisms to 5 mm diameter motor shafts. The set includes two hubs, two #4-40 set screws for securing the hubs to motor shafts, and one 0.05″ Allen wrench for use with the set screws. Each hub has four threaded mounting holes for #4-40 screws (not included).
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 #4-40 screws (not included), letting you mount custom wheels or mechanisms to your motors. The two included #4-40 hex set screws (one for each hub) allow secure coupling of shaft to hub, and a 0.05″ hex wrench (often the smallest size in SAE Allen wrench sets) is included for use with the set screws.
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.
