SpinBox, 1:1.67 Ratio

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 run times in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thoroughly grease the gear teeth periodically to ensure smooth operation.

This compact gearbox is designed to provide one reduction from the input motor. The output shaft is well secured, and has a 1/2" output diameter. This gearbox comes standard with an overdrive gear set, with a 35 tooth CIM gear and 29 tooth output gear, providing a 1:1.67 speed-increasing (overdrive) ratio.

This gearbox is shipped un-assembled.

Two different shaft plates are included in this kit, allowing the user to mount it various ways. These two different shaft plates can be seen in the product pictures above.

Motor input can include one CIM motor, or one AM Planetary Gearbox.
