The KNSU2-70 is a plastic spur gear with a steel core, designed for high-torque applications with improved dimensional stability and temperature resistance. It has a module of 2, 70 teeth, a 60 mm bore, a 140 mm pitch diameter, a 144 mm outside diameter, a 34 mm total length, and a 20 mm face width. The gear uses MC602ST nylon fused to an S45C steel core via diamond-knurled surface bonding, achieving a maximum allowable torque of 27.7 N·m (2.82 kgf·m). It meets JIS grade N9 precision (JIS B1702-1:1998), has a 20° pressure angle, and standard full-depth teeth. The design eliminates the need for bolting, offering a clean appearance and resistance to thermal expansion. Weight is 1.79 kg.
