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.

Unhappy with build quality September 8, 2017
Reviewer: Kantonsschule Glarus Fridolins Robotik from Glarus, Glarus Switzerland  
We used mecanum wheels in the 2017 season for the first time and didn't have experience with the drive train before that. Since we are a Swiss team and have limited order possibilities we figured we could just order the ones from AndyMark. We were happy with the other products that we ordered here. But for the price these mecanum wheels have a terrible build quality. Both wheels weren't bolted together properly and had an offset. We had to file them to fit on our wheel mount.
We ended up buying the VEX Pro 6" mecaum wheels after we had searched for alternatives.

(AndyMark response: Thank you for this feedback.  We are sorry that these wheels had these problems.  We are continuing to improve our quality as we ship products out to customers.  We will be contacting you to see if you need any further assistance.)

6" Mecanum Wheel HD, Set of 4 Wheels February 5, 2013
Reviewer: Nelson Stayton from Bartlesville, OK United States  
None of the rollers on the wheels would turn freely. We had to disassemble all four and use an aligning reamer in order to get the sleeve to move freely. We had the same problem last year with the 8 inch Mecanum wheels. Placing a screw in the sleeve and tapping on the wheel did not work. Poor quality control.
