For further technical details or to purchase the full standard, you can visit the Japanese Standards Association (JSA).
Without access to the actual , you cannot correctly calculate these tolerances because they are module- and diameter-dependent.
This standard specifies the permissible deviations and tolerances for individual parameters of cylindrical gear flanks. In simpler terms, it defines how accurate a gear tooth must be based on its intended application, size, and quality class.
The PDF version of JIS B 1702-1 typically includes the following sections:
For engineers, quality control managers, and procurement specialists searching for a the goal is usually the same: to obtain the official Japanese Industrial Standard for the accuracy of cylindrical gears. But simply downloading a PDF is only the first step. Understanding the standard’s history, structure, classes, and real-world application is what ensures compliance and performance.
