KPSA3-40J35 is a plastic spur gear from the KPSA series, with a module of 3, 35 teeth, and a bore size of 35 mm. It features a standard full-depth tooth profile with a 20° pressure angle, standardized keyway dimensions of 10 mm width by 3.3 mm depth per JIS B1301 (Js 9 tolerance), and is made of MC901 nylon. The gear has an outside diameter of 111 mm, a face width of 30 mm, and a permitted torque of 0.37 kgf·mm. Precision complies with JIS grade N9 (JIS B1702-1:1998). Dimensional stability is affected by temperature and humidity, and use with steel gears is recommended to mitigate heat buildup without lubrication.
