This planetary gearbox is a direct replacement to the gearbox found on the 7202 Series, 7203 Series and 7204 Series Yellow Jacket Planetary Gear Motor. This gearbox is packed with features, such as the Sheen Robotics pattern in the face, clearance cuts for nearby components, and a beefy 8mm REX output shaft to drive your favorite 8mm REX components! The 36mm diameter gearbox contains all steel larger gears . The screws which mount the gearbox are larger in diameter and come in from the sides. This helps make them ultra-resistant to loosening over time. Though the gearbox itself is larger, the shape of the head has been designed to allow more room for nearby components. an 80mm long output shaft. The longer shaft is able to reach through the channel and enough past the far side to fasten a hub and a wheel to, negating the need for a coupler and an additional shaft.
