KMSGA3-18 is a module 3, 18-tooth ground spur gear made of SCM415 with overall carburizing heat treatment resulting in a hardness of 55~60 HRC. It has a precision grade of JIS N5 per JIS B1702-1:1998, a 20° pressure angle, and standard full-depth teeth. The gear has a bore hub diameter of 36 mm, pitch diameter of 54 mm, outside diameter of 60 mm, face width of 30 mm, hub width of 15 mm, and total length of 45 mm. The allowable torque is 328 N·m (33.4 kgf·m), with a theoretical backlash range of 0.12~0.22 mm and a weight of 25.2 kg. The keyway is sized 6 mm × 2.8 mm with a web thickness of 0.61 mm. No secondary operations are permitted due to the carburized surface. The gear conforms to JIS grade N5 precision standards and is categorized under S1 mounting configuration.
