The KSSAG2-40 is a ground spur gear with a module of 2, 40 teeth, and an S45C carbon steel body. It features induction-hardened teeth with a hardness of 50 to 60 HRC and a black oxide surface treatment except on the teeth. The gear has a pitch diameter of 80 mm, an outside diameter of 84 mm, a face width of 20 mm, and an allowable torque of 98.3 N·m for bending strength and 72.1 N·m for surface durability. Backlash ranges from 0.10 to 0.20 mm, and the weight is 0.75 kg. It is manufactured to JIS Grade N7 precision per JIS B1702-1:1998. The gear is designed for keyway mounting with a bore tolerance of H7, though hardening degrades this tolerance. Secondary operations are prohibited on tooth areas.
