The KSSG series consists of module 1 ground spur gears made from S45C steel with induction-hardened tooth surfaces, 20° pressure angle, and precision grade JIS N7. The 42-tooth variant has a 12 mm bore, 42 mm pitch diameter, 44 mm outside diameter, 18 mm face width, 8 mm hub width, 1.8 mm keyway width by 3.3 mm depth, a 4 mm set screw, allowable torque of 10.5 N·m (1.07 kgf·m), backlash of 0.08~0.16 mm, and weighs 1.3 kg. Secondary operations on tooth areas are prohibited due to induction hardening. The J-series designation corresponds to precision grade equivalent to JIS N7.
