Found in the PDF's section on "Pitch deviations." If your gear has high Fp, it will vibrate. The JIS table provides exact micrometers (µm) of error allowed based on pitch diameter and grade.
Do you need a specific or tolerance table breakdown for a particular gear module? jis b 1702-1 pdf
The older JIS B 1702 (1976) system used Grades 0 to 8. The revised JIS B 1702-1 system uses Grades 4 to 12 , mirroring ISO. Found in the PDF's section on "Pitch deviations

Tables defining allowable deviations for different gear accuracy grades.
For engineers, quality control managers, and procurement specialists, the hunt for the "JIS B 1702-1 PDF" is a common yet critical task. But why is this document so vital? Is a free PDF download safe to use? And how does this standard compare to its international counterparts like ISO or DIN?
It’s also worth noting that a gear's final quality often involves other complementary standards. For example, while JIS B 1702-1 specifies the tooth accuracy, the dimensional tolerances for features like the shaft bore often adhere to another standard, , Class m (intermediate), to ensure the overall component is properly defined .
