The KPSA2-55J25 is a plastic spur gear with a module of 2 and 55 teeth, designed for metric applications. It features a finished bore of 25mm and is made from MC Nylon, which provides a balance of strength and lightweight characteristics. The gear has a pressure angle of 20¬8 and standard full depth teeth, ensuring compatibility with other gears in similar applications. The tooth hardness is rated between 115 to 120 HRR, indicating good wear resistance. It is important to note that plastic gears can experience dimensional changes due to temperature and humidity variations, which may affect performance. The allowable torque values are calculated based on assumed usage conditions, and it is recommended to use these gears in conjunction with steel gears to mitigate heat generation without lubrication. This product is suitable for applications requiring lightweight and corrosion-resistant components.
