KMSGA4-45 is a ground spur gear with a module of 4 and 45 teeth, designed for power transmission in precision applications. It has a bore diameter of 80 mm, outside diameter of 188 mm, face width of 40 mm, and total length of 60 mm. The gear is made of SCM415 steel with overall carburizing heat treatment, resulting in a surface hardness of 55-60 HRC. It meets JIS grade N5 precision standards (JIS B1702-1: 1998) and has a pressure angle of 20°. The allowable torque is 8.17 N·m (83.5 kgf·m), with a theoretical backlash of 0.16-0.26 mm. The keyway is dimensioned to JIS Js9 tolerance. No secondary operations are permitted due to the carburizing process.
