When utilizing the PDF, always verify the on the cover page, as periodic updates are released to accommodate advancements in CMM inspection technologies and manufacturing tolerances.
To determine the allowable limits for a specific gear using the standard, you need three primary pieces of data: : The metric module of the gear (e.g., Pitch Diameter ( ) : The reference diameter of the gear.
While still referenced in older technical documents, it is important to ensure that new projects use the 2016 version for the latest specifications. Conclusion New JIS Standards between Grade 4 and Grade
The updated standard inverted and expanded the scale. It introduces , where:
