The KPSA2.5-40J20 is a 40-tooth hubless spur gear made from nylon, specifically designed for applications requiring lightweight and corrosion-resistant components. It features a module of 2.5 and a finished bore diameter of 20mm, allowing for easy integration into various mechanical systems. The gear has a pressure angle of 20 degrees and is manufactured to JIS grade N9 precision standards, ensuring reliable performance in precision applications. The tooth hardness ranges from 115 to 120 HRR, providing adequate strength for moderate load applications. This gear is suitable for use in environments where plastic gears are preferred due to their lower weight and noise characteristics compared to metal gears. However, it is important to consider that plastic gears can be sensitive to temperature and moisture, which may affect their dimensional stability.
