The KNSU2 series consists of plastic spur gears with a steel core, designed for high torque transmission and dimensional stability under varying temperatures. The gears feature a 2 mm module, 20° pressure angle, and JIS grade N9 precision, with MC602ST nylon molded onto an S45C steel core using a mechanical interlock process. The KNSU2-50 variant has a 50-tooth count, 100 mm pitch diameter, 104 mm outside diameter, 20 mm face width, and a 60 mm hub diameter. The allowable torque is 18.8 N·m (1.92 kgf·m), and the weight is 0.90 kg. The bore diameter is fixed at 60 mm for this variant, and backlash is specified as 0~0.44 mm. The design supports operation up to 140°C with minimal dimensional change.
