1999-POLOLU Universal Aluminum Mounting Hub for 6mm Shaft, M3 Holes (2-Pack)

These universal aluminum mounting hubs allow you to mount custom wheels and mechanisms to 6 mm diameter motor shafts. The set includes two hubs, four M3 set screws for securing the hubs to motor shafts, and one 1.5 mm 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 6 mm 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, 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.

The picture to the right shows a hub with Pololu’s 19:1 metal gearmotor 37Dx52L mm and a Pololu stamped aluminum L-bracket for 37D mm metal gearmotors. These hubs will work with any of our 37D mm metal gearmotors, and they also work with 80 mm and 90 mm Pololu wheels.
