4" HiGrip Wheel, 60A Durometer Black

Churro is a versatile extruded aluminum hex profile. The outside of this part is a 1/2 in. hex with small concave dimples which act as weight savings. There is an inside hole is sized at 0.2 in. in order to fit 1/4-20 thread forming screws. No tapping or threading is needed, as long as a thread forming screw is used. The outside hex size fits a 1/2 in. wrench or socket. 

The 3-foot churro, our most popular length and the best value on shipping, is available anodized in red, blue, purple, gold and black to dress up your robot. Anodized finish is hardy and doesn't flake off or add thickness like paint, but it is possible for a scratch to expose the bare metal beneath. Take basic precautions in your shop like watching for sharp tools or overtightening this churro in a vise.

This 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.
