The KNSU3 series consists of plastic spur gears with a steel core, using MC602ST nylon and an S45C metal hub, designed for high-temperature applications and dimensional stability. The gear has a module of 3, 28 teeth, a pitch diameter of 84 mm, an outside diameter of 90 mm, a face width of 30 mm, and a total length of 50 mm. The bore diameter is 50 mm, with a hub width of 17 mm. Precision conforms to JIS grade N9 (JIS B1702-1:1998). The allowable torque is 30.5 N·m (3.11 kgf·m), and backlash is specified as 0 to 0.54 mm. The nylon is fused to the core via a diamond-knurled surface treatment, eliminating mechanical fasteners. The part weighs 0.79 kg.
