Low precision (hand-operated machinery or slow-speed gears). Key Definitions in JIS B 1702-1

: Governs radial composite deviations and runout tolerances.

: Governs radial composite deviations and runout data, analyzing gears through double-flank mesh testing.

: Manufacturers like KHK Gears and QTC Metric Gears provide technical catalogs that explain how these JIS standards apply to specific gear products. jis b 1702-1 pdf

When checking an engineering drawing or a CNC gear metrology chart, JIS B 1702-1 centers on three core elemental measurement categories: Pitch Deviations Single Pitch Deviation ( fptf sub p t end-sub

Since JIS B 1702-1 was largely harmonized with ISO 6336, you can use the standards (which are much easier to find online) as a baseline. The "useful paper" you need is one that highlights the specific deviations (usually in the load factors $K_H$ and $K_F$ or the stress correction factors). Low precision (hand-operated machinery or slow-speed gears)

The standard, officially titled "Cylindrical gears — ISO system of flank tolerance classification — Part 1: Definitions and allowable values of deviations relevant to flanks of gear teeth", is a critical document in the world of mechanical engineering. Published by the Japanese Standards Association (JSA) , it defines a comprehensive tolerance classification system for the tooth flanks of individual cylindrical involute gears.

If you need the actual standard for certification or legal compliance:

A legacy standard that used different terminology and ranking (e.g., Grade 4, Grade 5). Always check if your drawings are referring to the 1976 (obsolete) or the 1702-1:1998/2016 (modern) standard. Importance of Accessing the PDF Document : Manufacturers like KHK Gears and QTC Metric

A genuine copy of the standard includes these essential sections:

The standard provides allowable values for several critical gear metrics: Single Pitch Deviation (

Engineers and technicians seek the PDF version for several practical reasons:
