Plastic spur gears with a steel core, available in module 3, feature a 15-tooth count, a 50 mm pitch diameter, a 84 mm outside diameter, a 30 mm face width, and a 17 mm hub width, with a JIS grade N9 precision rating and a 20° pressure angle. The gear uses MC602ST nylon molded onto an S45C steel core with a diamond-knurled surface for enhanced bonding, ensuring dimensional stability across temperature extremes and eliminating the need for mechanical fasteners. The allowable torque for this module is 30.5 N·m (3.11 kgf·m), and the backlash is 0~0.54 mm. The part is designed for applications requiring high thermal resistance and clean mechanical appearance.
