The KNSU2-28 is a plastic spur gear with a steel core, module 2, 28 teeth, and a pitch diameter of 56 mm. It features a 35 mm bore, 20 mm face width, and 34 mm total length. The gear uses MC602ST nylon fused to an S45C steel core via a diamond-knurled surface for high holding strength. It has a pressure angle of 20°, standard full-depth teeth, and meets JIS grade N9 precision (JIS B1702-1: 1998). The allowable torque is 9.05 N·m (0.92 kgf·m), with a backlash range of 0-0.44 mm. The gear is designed for use with metal mating gears to avoid heat buildup from plastic-on-plastic contact.
