Plastic spur gears in the KPS1 series are made of MC901 nylon with a 20° pressure angle and standard full-depth teeth, certified to JIS grade N9 (JIS B1702-1: 1998). The 90-tooth variant has a 10 mm face width, 102 mm outer diameter, 20 mm hub width, and a 40 mm hub diameter. The table lists screw sizes for bore sizes of 5 mm and 6 mm, with corresponding torques up to 0.079 N·m; a 14 mm bore is not documented for the 90-tooth gear, but the series supports bore sizes tailored to screw thread requirements. Backlash is specified as 0.36 mm, and dimensional stability may be affected by temperature and humidity as a characteristic of MC nylon gears.
