KMSGB2.5-30 is a ground spur gear with a module of 2.5, 30 teeth, and a bore keyway of 12 mm width by 3.3 mm depth. It is made of SCM415 steel with overall carburizing heat treatment, resulting in a hardness of 55 to 60 HRC. The gear has a pressure angle of 20°, standard full-depth teeth, and complies with JIS grade N5 precision (JIS B1702-1:1998). It has a pitch diameter of 75 mm, outside diameter of 80 mm, face width of 25 mm, hub width of 12 mm, total length of 37 mm, and weighs 0.87 kg. The allowable torque is 322 N·m (32.8 kgf·m), and theoretical backlash ranges from 0.12 to 0.22 mm. No secondary operations are permitted due to the carburized surface.
