This report examines ANSI/AGMA 2015-1-A01, a critical American National Standard that fundamentally changed how the precision of cylindrical gears is measured and classified. Core Function & Purpose
The AGMA 2015-1-A01 document typically covers:
Marcus looked at the title: Accuracy of Gears - Part 1.
The standard provides a unified system to correlate gear accuracy grades with specific tooth tolerances. Its primary applications include:
If you see “20151A01” in a company internal document or old drawing, it’s almost certainly a typo for 2015-A01.
As of this writing, a "B" revision (e.g., 20151-B05) has not been issued. The A01 version remains the current metric bevel gear rating standard. However, always verify at the AGMA store before purchase.
