Just 'Cuz Pro 24mm Gearboxes + Shafts

Ultimate Toughness With Several Ratios!

Our Pro 24mm Gearbox has arrived to take your combat robot to the next level! 

Pro 24mm gearboxes are built to last with the best materials available. One-piece, hardened alloy steel 6mm diameter output shaft, dual ball bearing shaft support, machined aluminum outer construction, with all steel internal gears. M3 threaded face mounting, with a lightened square faceplate perfect for keying into a 3D-printed chassis. Motor mount plates with added ribs to keep the motor secure after the biggest impacts, and take shear load off the tiny mount screws. Big module 0.4 planetary gears for greater torque. While these Pro gearboxes are larger than our lightweight DartBox V2 square gear motors, they compensate for that with a vastly more rugged design. 

Built for 3lb “Beetleweight” combat robots, and plenty of other applications. The price shown is for one gearbox, assembled plus 1 pinion gear.  Each pinion gear is a brass mod 0.4 gear which is 3mm long and has a bore diameter to press fit onto a 2mm shaft.
