KSSG2.5-80J50 is a ground spur gear with a module of 2.5, 80 teeth, and a 50 mm bore, designed for precision mechanical drive applications. It has a pitch diameter of 200 mm, outside diameter of 205 mm, face width of 25 mm, and total length of 43 mm. The gear is made from S45C steel with induction-hardened tooth surfaces achieving 50-60 HRC hardness. Precision conforms to JIS grade N7 (JIS B1702-1: 1998). The keyway is 14 mm wide by 3.8 mm deep, complying with JIS B1301 Js9 tolerance. Allowable torque is 637 N·m (65.0 kgf·m). Backlash is specified as 0.14-0.24 mm. A set screw is included for mounting. Secondary operations on the tooth profile are not permitted due to induction hardening.
