Product Overview:
4 inch, HEAVY DUTY Mecanum wheel set, these come assembled as shown in the picture. This is a set of 4 wheels, consisting of 2 "right" wheels and 2 "left" wheels.

The interior body of this wheel is made of molded black poycarbonate, 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.

Great Customer Service February 9, 2017
Reviewer: Mark Moulton from La Crescent, MN United States  
The wheels came and they are great, however the best part was their service.  One of the wheels came with a slight defect (it happens, 99% of the stuff I have ordered has been perfect), the roller was not completely smooth due to a defect.  I contacted them and got a reply within 1 hour and they offered to send out some replacements free of charge.  I had another order on the way and they slipped them in that package.  I was really happy with how it all turned out.

Missing parts? January 3, 2017
Reviewer: L Mukho from San Jose, CA  
We received the box from AndyMark today, and we were hoping to use the Mecanum wheels with the Tetrix DC Motor. In the box, there were 2 left wheels and 2 right wheels. Were we supposed to receive anything else, such as metal plates or hubs or brass tubes? Because we are not sure how to attach the motor axles to these wheels.

(AndyMark Response: Feel free to contact support@andymark.com at any time for assistance with how to attach our gearboxes and wheels.)
