KSSAG2.5-32 is a metric spur gear with a module of 2.5, 32 teeth, and a bore diameter of 20 mm, made from S45C carbon steel with induction-hardened tooth surfaces achieving 50 to 60 HRC hardness. It has a pitch diameter of 80 mm, an outside diameter of 85 mm, a face width of 20 mm, and weighs 0.92 kg. The gear is black oxide coated except on the tooth surfaces, and its allowable bending strength is 90.1 N·m with a surface durability torque of 14.7 N·m. Backlash is between 0.10 and 0.20 mm. The part conforms to JIS grade N7 per JIS B1702-1:1998 and is designed for use with an H7 bore tolerance, though the bore tolerance degrades after hardening. Secondary operations are prohibited on the tooth areas due to induction hardening.
