Product Overview

This version of the wheel can handle a 200 pound load. The interior body of this wheel is made of molded black polycarbonate, 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. Wheels ship assembled.

Product Usage:
For a mecanum drive system to work you must use two right and two left wheels.

Included Hardware:Roller and Axle Design:
The gray urethane rubber roller (am-3027) has a durometer rating of 80A. The roller has a Nylon core, and rides on a stationary brass tube.

Wheel Structure:
9 rubber rollers are sandwiched between 2 steel plates. The steel plates are riveted to two interior polycarbonate hubs, which form the interior of the wheel. The two interior pieces are held together by the fastening technique of the rollers being attached. These wheels can be purchased in a set of 4 (2 rights, 2 lefts), or individually. They are sold without hubs, sprockets, or bearings.
