Nano Tube 20, Two 1/2 in. Key Shafts, 1 motor input

Product Usage:
All AndyMark gearboxes require grease for proper operation and long life. We suggest using our red tacky grease, am-2768. We also encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short runtimes in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thorough grease of the gear teeth periodically to ensure smooth operation.

This 20-in.-long Nano Tube can house two complete gearboxes, each having the same gearing and shafts as the Nano with 500 Key Shaft. This Toughbox Nano Tube accepts one CIM Motors. Hardware is included for attaching this motor. Individual Parts can be bought separately to accept two CIM Motors.

This product is intended to be used as a complete drive module for the side of a 2-wheel-drive robot. A second tube is to be used on the opposite side of the robot in order to make the complete drive chassis.
