The KPS1-40J12 is a plastic spur gear in the KPS1 series, characterized by a module of 1, 40 teeth, a 12 mm finished bore, and 6 mm hub width, constructed from MC901 nylon. The gear has a pitch diameter of 40 mm, an outside diameter of 42 mm, a face width of 10 mm, and a total length of 20 mm, with a keyway dimension of 4 x 1.8 mm and an M4 set screw. It has an allowable torque of 1.48 N·m (0.15 kgf·m) and a theoretical backlash of 0-0.34 mm. The gear meets JIS B1702-1:1998 precision grade N9 and operates with a 20° pressure angle. Dimensional stability is subject to temperature and humidity changes, and operation without lubrication is discouraged. The set screw tightening torque must not exceed 0.12 N·m for safety and thread integrity.
