The KNSU3 series consists of plastic spur gears with a steel core, using MC602ST nylon and an S45C metal hub, designed for high-temperature operation and dimensional stability. The gear has a module of 3, 22 teeth, a 38 mm bore, a pitch diameter of 66 mm, an outside diameter of 72 mm, a face width of 30 mm, and a total length of 47 mm. It is precision-ground to JIS grade N9 (JIS B1702-1: 1998) with a 20° pressure angle and standard full-depth teeth. The allowable bending strength is 22.5 N·m (2.29 kgf·m), with a theoretical backlash of 0-0.54 mm and a weight of 0.46 kg. The core is bonded using a diamond knurling and groove process for superior holding strength. The series operates reliably at temperatures up to 140°C with minimal thermal expansion.
