KSSAG2-25 is a ground spur gear with a module of 2, 25 teeth, and a bore size specified by the J-series suffix. It features S45C carbon steel with induction-hardened teeth (50 to 60 HRC), black oxide surface treatment except on the teeth, and a face width of 15 mm. The gear has a pitch diameter of 50 mm, an outside diameter of 54 mm, and an allowable torque of 27.0 N·m for bending strength and 13.7 kgf·m for surface durability. Backlash ranges from 0.10 to 0.20 mm, and the weight is 0.28 kg. The gear precision meets JIS grade N7 per JIS B1702-1:1998, and the bore tolerance is H7, though this degrades after hardening.
