2 Rubber Wheel 42mm(D) x 19mm(W)
This custom-designed plastic wheel has a rubber tire measuring 1.65″ (42 mm) in diameter and is designed to fit the output shafts on the Solarbotics GM11a/12a/13a/14a/18 style gearmotors.
An interesting feature offered are the teeth on the inside of the hub can be used with a reflector sensor for encoder feedback.
These gearmotors should be mounted onto the side of the hub with the protruding teeth. The output shaft will slide into the socket easily at first but will achieve a snug fit when pressed through to the other edge of the hub.
IMPORTANT: These wheels These wheels were designed to fit on their 9mm long motor shafts. As the Solarbotics shafts are a bit short (8mm), you may find better results by shaving off ~ 1mm of the hub interior so you can firmly set the set the shaft. Or mount the motor from the other side!
