Steel hubless spur gear with a module of 1.5, 70 teeth, and a tooth width of 15 mm, designed for metric applications. It has a standard full-depth tooth profile with a 20° pressure angle and is made from S45C steel. The gear meets JIS grade N8 precision (JIS B1702-1:1998). The theoretical backlash is between 0.14 mm and 0.32 mm, and the allowable torque is 16.6 N·m (1.69 kgf·m). The part is machined to a bore size consistent with the S5 series, though the exact bore dimension for KSSA1.5-70 is not specified in the table. Backlash values are for a pair of identical gears in mesh.
