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 #4-40 screws (not included), letting you mount custom wheels or mechanisms to your motors. The four included #4-40 hex set screws (two 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.
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 mmPololu wheels.
