KSSY1-120 is a steel thin face spur gear with module 1, 120 teeth, and a bore diameter of 120 mm, designed for precision gearing applications. It has a 20° pressure angle, standard full-depth teeth, and is made from S45C steel with a tooth hardness of less than 194HB. The gear is 14 mm wide and 6 mm thick, with a keyway sized for JIS B1702-1:1998, JIS Bs 9 tolerances. Its allowable torque is 32.1 N·m (3.27 kgf·m), and theoretical backlash ranges from 0.08 to 0.18 mm. The product adheres to JIS grade N8 precision standards. Caution is advised against secondary operations that reduce tooth width due to inherent thinness and risk of deflection.
