The KPSA2.5-40J28 is a plastic spur gear with a module of 2.5 and 40 teeth, designed for precision applications. It features a finished bore of 28mm and is made from MC901 nylon material, which provides a tooth hardness of 115 to 120 HRR. The gear has a pressure angle of 20¬8 and is classified under JIS grade N9, indicating a high level of precision. This gear is suitable for applications where lightweight and corrosion-resistant components are advantageous. However, it is important to note that plastic gears can be sensitive to temperature and humidity, which may lead to dimensional changes. The allowable torque for this gear is specified, and it is recommended to use lubrication to prevent heat generation when paired with other gears. Engineers should consider the KPSA2.5-40J28 for projects requiring a reliable and precise plastic gear solution, keeping in mind the environmental conditions that may affect its performance.
