Product Overview:
6 inch, HEAVY DUTY Mecanum wheel set

This is a set of 4 wheels, consisting of 2 "right" wheels and 2 "left" wheels. All 4 wheels are required to make a Mecanum drive holonomic system to work properly.

This version of our Mecanum wheel can handle a 200 pound load at each wheel. The interior body of this wheel is made of 1/8 inch thick stamped aluminum, while the perimeter side plate is made of 1/8 inch thick steel, zinc plated. The perimeter plate is riveted to the interior body, and each perimeter bent tab rests on the interior body rim. This support allows for the wheel to handle more load.
