Plastic spur gears with a steel core, available in module 3 with 34 teeth, feature a 60 mm bore diameter, 102 mm pitch diameter, 108 mm outside diameter, 30 mm face width, and 47 mm total length. The gear is made of MC602ST nylon with an S45C metal core, complies with JIS grade N9 (JIS B1702-1:1998) for precision, and has a 20° pressure angle. The allowable torque is 39.0 N·m (3.98 kgf·m), with a theoretical backlash of 0-0.56 mm. The design ensures strong fusion between nylon and steel via a diamond-knurled core, providing dimensional stability across a wide temperature range and eliminating the need for mechanical fasteners.
