KSS2-38J15 is a steel spur gear with a module of 2, 15 teeth, and a 15 mm bore, designed for use in mechanical power transmission. The gear features a standard full-depth tooth profile with a 20° pressure angle, manufactured from S45C steel, and meets JIS grade N8 precision (JIS B1702-1: 1998). It has a keyway conforming to JIS B1301 (Js 9 tolerance) and is supplied with a set screw. The gear width is 5 mm, and the nominal weight is 0.85 kg. Backlash is specified as 0.14~0.30 mm in normal direction for a matched pair, and allowable torque is 0.85 N·m based on assumed usage conditions. Secondary operations narrowing tooth width are cautioned against due to potential impacts on precision and strength.
