Plastic spur gears with a steel core, designed for high-temperature and high-strength applications, are available in module 2.5 with a 30-tooth configuration. The gear features a 45 mm bore, 75 mm pitch diameter, 80 mm outside diameter, 25 mm face width, and 50 mm total length, with a JIS grade N9 precision rating and 20° pressure angle. The MC602ST nylon is fused to an S45C steel core using a diamond knurling and molding process, ensuring strong adhesion and dimensional stability across temperature ranges up to 140°C. The allowable torque is 19.2 N·m (1.96 kgf·m), with a backlash range of 0-0.46 mm. The design eliminates mechanical fasteners for a clean appearance and improved reliability.
