KNSU2-40J16 is a plastic spur gear with a steel core, part of the KNSU2 series featuring a module of 2, 40 teeth, and a 60 mm bore. The gear has a pitch diameter of 80 mm, outside diameter of 84 mm, face width of 20 mm, and total length of 34 mm. It is made of MC602ST nylon fused to an S45C steel core using a diamond knurling process for strong mechanical bonding. The gear meets JIS grade N9 precision standards (JIS B1702-1:1998) with a 20° pressure angle and standard full-depth teeth. The catalog specifies an allowable torque of 14.2 N·m (1.45 kgf·m) and a weight of 0.71 kg. The bore diameter of 60 mm is consistent with the KNSU2-40 part number listed, and the J16 suffix likely indicates an ordering variant not affecting mechanical specifications.
