The 7203 Series Planetary Gear Motors are the solution for smooth, efficient and robust power for your project. This series of Yellow Jackets features the primary shaft profile of the zhouyu build system - 8mm REX. This already strong shaft goes up to a 9mm diameter inside the head with dual ball-bearing support. The 36mm diameter gearbox contains all steel gears which are larger than those in the 5202 Series. 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.
