Plastic spur gears with a steel core, module 3, 48 teeth, and a 70 mm bore diameter, designed for high torque transmission. The gear has a 144 mm pitch diameter, 150 mm outside diameter, 30 mm face width, and a total length of 105 mm. Made of MC602ST nylon with an S45C steel core, it meets JIS grade N9 precision (JIS B1702-1:1998) and has a 20° pressure angle. The allowable torque is 60.2 N·m (6.14 kgf·m), with a theoretical backlash of 0 to 0.56 mm. The gear is manufactured with a diamond-knurled steel core to ensure strong bonding with the nylon, providing dimensional stability and performance across wide temperature ranges. Weight is approximately 1.05 kg.
