QTC METRIC GEARS Plastic Spur Gears (metric) KPS1-80J19

The KPS1-80J19 is an 80-tooth nylon spur gear featuring a hub and a finished bore of 19mm. It is constructed from MC Nylon, which provides a balance of strength and lightweight properties suitable for various applications. The gear has a standard full depth tooth design with a pressure angle of 20 degrees, ensuring compatibility with other gears that meet these specifications. The precision grade is classified as JIS grade N9, indicating a high level of accuracy in manufacturing. This spur gear is designed for applications where plastic gears are preferred due to their lower weight and noise levels compared to metal gears. However, it is important to note that significant variations in temperature or humidity can affect the dimensions of plastic gears, including bore size and backlash. The allowable torque values are calculated based on assumed usage conditions, and it is recommended to consider the specific application environment when selecting this gear. Engineers should also be aware that using plastic gears in pairs without lubrication may lead to heat generation and dimensional changes. The KPS1-80J19 is suitable for applications requiring a lightweight gear solution, but careful consideration of environmental factors and load conditions is advised.
