The KPS1.5 series consists of plastic spur gears made from MC901 nylon with a 20° pressure angle and standard full-depth teeth, conforming to JIS grade N9 (JIS B1702-1:1998) precision. The gear has a module of 1.5, 40 teeth, and a finished bore of 18mm. It includes a hub and is designed for use with steel gears to mitigate heat generation. Backlash values are theoretical and based on meshing with an identical gear. Allowable torque and dimensional tolerances are listed for the series, with bore tolerance specified as H8. Secondary operations are cautioned due to sensitivity to temperature and moisture. Keyways follow JIS B1301 Js9 tolerance. Set screws are included for tapped holes, with torque limits of 0.12N·m for M4 and 0.38N·m for M5 when applicable.
