4" DuraOmni Wheel with 1/2" id bearings. This new heavy duty omni wheel is a vast improvement over our older 4" omni wheels and other wheels on the market. The body has been totally redesigned with durability and mobility in mind. The design intent is to provide a smooth roll along with the ability to handle impacts very well.
The body is made from black polycarbonate, while the rollers are each molded with a nylon core and TPU tread. These rollers spin smoothly on a captured 1/8" x 1.875" dowel pin.
