This a single axle for our 13" tiller tires. The hub is welded to a steel 3/4" diameter shaft with a standard 3/16" keyway. It is intended to be chain driven. We use this shaft on our snow plow along with 3/4" pillow block bearings.
These wheels and shafts work great with our wheel chair motors. To calculate the speed of the robot just take the output RPM * wheel diameter (in inches) * 3.14 / 12 = feet per minute.
These shafts are made to order and may require a 2-4 business days before shipment.
