Pololu Universal Aluminum Mounting Hub for 5mm Shaft, #4-40 Holes (2-Pack)
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 #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. A dimension diagram of the hub is available under the resources tab.
Pololu wheels with 90, 80, 70, and 60mm diameters in three colors: blue, red, and yellow.
