Plastic spur gears with a steel core, offered in module 3, feature a 16 mm bore, 18 teeth, a 54 mm pitch diameter, and a 60 mm outside diameter. The gear has a 30 mm face width, 17 mm hub width, and 47 mm total length. It is constructed of MC602ST nylon with an S45C steel core, has a 20° pressure angle, standard full-depth teeth, and complies with JIS grade N9 (JIS B1702-1: 1998) and JIS grade 5 (JIS B1702: 1976). The allowable torque is 1.75 N·m (0.28 kgf·m), with backlash specified between 0 and 0.54 mm. The holding strength between the nylon and core is achieved by a diamond-knurled steel surface treated prior to casting, ensuring dimensional stability and high-temperature performance up to 140°C. Weight is 0.28 kg.
