KSS8-12 is a steel spur gear with module 8, 12 teeth, and a plain bore, conforming to JIS grade N8 precision (JIS B1702-1:1998). The gear has a 20° pressure angle, is made of S45C steel, and has a tooth hardness of less than 194HB. It measures 75mm in bore diameter, 96mm in outside diameter, and 112mm in width, with a weight of 6.39 kg. The allowable torque is 975 N·m (62.6 kgf·m), and the backlash range is 0.28~0.58 mm. Secondary operations that reduce tooth width are discouraged due to potential impacts on precision and strength.
