KMSGA1-70 is a ground spur gear with a module of 1, 70 teeth, and a 20° pressure angle, manufactured from SCM415 steel with overall carburizing to a hardness of 55-60 HRC. It conforms to JIS grade N5 (JIS B1702-1: 1998) and has a face width of 10 mm, a bore diameter of 45 mm, and a keyway of 6 mm width by 2.8 mm depth. The gear has a pitch diameter of 70 mm, an outside diameter of 72 mm, and a total length of 20 mm. It provides an allowable bending strength of 71.9 N·m and allowable surface durability of 111 N·m, with a theoretical backlash of 0.10-0.18 mm. The gear is designed for parallel shaft applications and cannot undergo secondary operations due to its heat-treated surface.
