Plastic spur gears with a steel core, designed for mechanical power transmission, are available in a module 1 configuration with a 40-tooth count, a 25 mm bore diameter, a 40 mm pitch diameter, a 42 mm outside diameter, and a 10 mm face width. The part includes an S45C metal core and MC602ST nylon teeth, with a pressure angle of 20° and JIS grade N9 precision. It has an allowable torque of 2.06 N·m (0.21 kgf·m), a theoretical backlash of 0~0.34 mm, and a weight of 0.12 kg. The gear is designed for operation across a wide temperature range with minimal dimensional change due to the full-surface fusion of nylon to the core.
