The Ranglebox Saturn planetary gearbox is a highly versatile 2-stage 19:1 epicyclic reducer for motors with a 5mm shaft. It features M5 mounting holes on 3 sides, dual bearings supporting a ⌀12mm keyed output and 4 standard motor mounting patterns. This is the ideal heavy duty transmission solution for any mid-size robotics project!

The Saturn gearbox sandwiches an all-steel gearset with 6061-T6 aluminium endplates, fastened with all high tensile hardware. A pair of premium DUNLOP bearings ensure the toughness extends to the output shaft, which by the way, is replaceable!
