It has a JIS grade N9 precision rating, a 20° pressure angle, and is made of MC602ST nylon with an S45C steel core. The allowable torque is 15.3 N·m (1.56 kgf·m), with a backlash range of 0-0.46 mm and a weight of 0.33 kg. The gear uses a proprietary process where the metal core is diamond-knurled and grooved before nylon casting to ensure strong fusion, providing dimensional stability across temperature variations and a clean appearance without mechanical fasteners.
