Plastic spur gears with a steel core, available in module 3, feature a standard full-depth tooth profile, 20° pressure angle, and are made of MC602ST nylon with an S45C steel core. They meet JIS grade N9 (JIS B1702-1:1998) precision standards. The gear has a 43mm bore, 72mm pitch diameter, 78mm outside diameter, 30mm face width, and 17mm hub width, with an allowable torque of 25.1 N·m (2.56 kgf·m).
