KSSG2.5 series ground spur gears are metric gears with a module of 2.5, 20° pressure angle, and S45C steel construction with induction-hardened tooth surfaces at 50-60 HRC. They meet JIS grade N7 precision (JIS B1702-1:1998), have standard full-depth teeth, and are available with bore sizes from 8 mm to 14 mm and keyways according to JIS B1301 Js9 tolerance. The J28 variant has a 28 mm finished bore, 8×3.3 mm keyway, M6 set screw, and an allowable torque of 2.62 N·m (0.27 kgf·m) with 0.14-0.24 mm backlash. Total length is 125 mm, outside diameter is 120 mm, and face width is 25 mm. Secondary operations on tooth areas are prohibited due to induction hardening.
