KMSGA1.5-45 is a ground spur gear with a module of 1.5, 45 teeth, and a precision JIS grade N5 (JIS B1702-1: 1998). It is made of SCM415 steel with overall carburizing heat treatment, achieving a hardness of 55~60 HRC. The gear has a pitch diameter of 67.5 mm, outside diameter of 70.5 mm, face width of 15 mm, and a keyway of 5 x 2.3 mm. It has an allowable torque of 143 N·m (15.8 kgf·m) and a theoretical backlash of 0.10~0.18 mm. The total length is 25 mm and the web thickness is 10 mm. No secondary operations are permitted due to the carburizing process. The keyway dimensions follow JIS (Js9) tolerance, but deviations may occur from heat treatment effects.
