KNSU2-80 is a plastic spur gear with a steel core, module 2, 80 teeth, and a 60 mm bore. It has a pitch diameter of 160 mm, outside diameter of 164 mm, face width of 20 mm, and total length of 125 mm. The gear uses MC602ST nylon fused to an S45C steel core via a knurled surface process for strong mechanical bonding. It meets JIS grade N9 (JIS B1702-1:1998) precision standards, with a 20° pressure angle and standard full-depth teeth. The allowable torque is 32.0 N·m (3.27 kgf·m), and the backlash range is 0~0.46 mm. The gear is designed for high-temperature operation up to 140°C with minimal dimensional change due to the full-surface nylon bonding.
