KMSGA3-30 is a module 3, 30-tooth ground spur gear made of SCM415 steel with overall carburizing heat treatment, achieving 55-60 HRC hardness. It has a pitch diameter of 90 mm, outside diameter of 96 mm, face width of 30 mm, and keyway dimensions of 8 mm width by 3.3 mm depth. The allowable torque is 677 N·m (565 kgf·m), with a theoretical backlash of 0.12-0.22 mm and a weight of 69.1 kg. The gear meets JIS grade N5 precision (JIS B1702-1:1998) and has a pressure angle of 20° with standard full-depth teeth. It uses an S1 hub configuration with no web or keyway dimensions specified beyond the keyway size. Secondary operations are prohibited due to the carburizing process.
