The KNSU2.5-28J20 is a plastic spur gear with a module of 2.5 and 28 teeth, designed for applications requiring a lightweight yet durable component. It features a finished bore of 20mm, allowing for easy integration into various mechanical systems. The gear is constructed from MC nylon fused to a steel core, providing enhanced strength and dimensional stability across a wide temperature range. This design minimizes the risk of dimensional changes due to temperature fluctuations, making it suitable for environments where thermal variations are present. The gear's pressure angle is 20¬8, and it adheres to JIS grade N9 precision standards, ensuring reliable performance in precision applications. The product is particularly advantageous for use in pairs with steel gears, as it can generate heat and dilation when used without lubrication.
