The gear is made of MC901 nylon, has a 20° pressure angle, standard full-depth teeth, and a JIS grade N9 precision rating. It includes a keyway of 6 mm width by 2.8 mm depth conforming to JIS B1301 standards. The face width is 20 mm, the outside diameter is 44 mm, and the bore diameter is 20 mm. The allowable torque is 14.9 N·m (1.52 kgf·m), with a theoretical backlash range of 0 to 0.44 mm and a weight of 0.16 kg.
