The KSSG series consists of ground spur gears with a module of 1, 20° pressure angle, and S45C steel construction with induction-hardened tooth surfaces (50~60HRC). The KSSG1-30J12 corresponds to the 30-tooth variant with a 12mm bore, 30mm pitch diameter, 32mm outside diameter, 8mm face width, 4mm hub width, and 18mm total length. It features a keyway of 4mm width x 2.8mm depth and a set screw for shaft retention. Allowable torque is 8.11 N·m (0.83 kgf·m) with backlash ranging from 0.08 to 0.16 mm. The gear meets JIS Grade N7 precision (JIS B1702-1:1998). Secondary operations on tooth areas are prohibited due to induction hardening.
