The KNSU3-24 is a plastic spur gear with a steel core, featuring a module of 3, 24 teeth, a pitch diameter of 72 mm, an outside diameter of 78 mm, a face width of 30 mm, and a hub width of 17 mm. It has a plain bore with a hub diameter of 43 mm and a total length of 47 mm. The gear is made of MC602ST nylon with an S45C steel core, meeting JIS grade N9 precision (JIS B1702-1:1998) and JIS grade 5 (JIS B1702:1976). The pressure angle is 20°, with standard full-depth teeth and a backlash of 0~0.54 mm. The allowable bending torque is 25.1 N·m (2.56 kgf·m). The design fuses nylon to the steel core via a diamond-knurled surface treatment, ensuring strong bonding, dimensional stability across temperature ranges, and a clean appearance without mechanical fasteners.
