This is a wheel and shaft set for our 13" tiller tires. They come as a pair along with a pair of axles with a hub that mounts to the tires. The hub is welded to a steel 3/4" diameter shaft with a 3/16" keyway. We use this wheel and shaft set on our 4WD WC DB and 6WD WC DB All Terrain Robot Platforms 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.
Inflate tires before use! Underinflated tires can spin on the rim rupturing the tube inside.
You can add machine keys to this set for coupling sprockets to the shafts. There are two options for keys listed, a 0.75" long key and a 1.0" key. We use the 0.75" key with a #35 15 tooth sprocket and we use the 1.0" key with a #40 18 tooth sprocket.
These shafts are made to order and may require a 2-4 business days before shipment.
