This is a robot drive wheel we had made specifically for us. It does not have a bearing. It is 6 inches in diameter and 2 inches wide. It's a solid foam core with rubber treads and outer layer. The steel rim is painted black with a 4 bolt pattern so you can easily mount it to a flanged hub.
One pair of 10" wheels with aggressive treads and shafts. The shafts are machined steel with a welded hub. They are for our Heavy Duty and Enclosed Heavy Duty ATRs. These will not work for our Standard ATRs.
The GPS 18x is an OEM, high-sensitivity GPS sensor for use in automotive, fleet vehicle, and electronics applications that require a small, highly accurate GPS receiver.
