AGMA has helped to set national gearing standards since 1916. The association also serves the focal point within the United States for the development of ISO gearing standards. Today, this work is carried out by 23 Active Technical Committees. AGMA standards address nearly all the critical gearing topics, from load capacity and lubrication to accuracy and inspection.

How to Find Standards

Now you can easily view and purchase standards with the powerful search capability of AGMA’s Online Store. You no longer have to read through a long list. Instead, search the Store by the following fields:

  • Product Category - Choose to see AGMA Standards or ISO Papers. You also can specify AGMA Foundation Research Reports, AGMA Technical Papers or Software. 

  • Title Contains - If you only know part of the name of a standard, that’s all you need to get started. Simply type in keywords, such as “AGMA B01,” “ANSI” or “A01.”

  • Product Description Contains - Search all items in the store by your topic of interest. For example, type in “bevel” and click on “search” for a list of all national and international standards, technical papers and software related to bevel gears.

  • Browsing - Find out what’s new by viewing the Hot List – or enjoy Browse by Product Category.

Newest Released Publications

AGMA Releases New Standards on Flexible Couplings


The AGMA Technical Division is pleased to announce the publication of two new AGMA standards:

·         ANSI/AGMA 9003-C17, Flexible Couplings – Keyless Fits

·         ANSI/AGMA 9103-C17, Flexible Couplings – Keyless Fits [Metric Edition]


These standards present information on design, dimensions, tolerances, inspection, mounting, removal, and equipment that is in common use with keyless tapered and keyless straight (cylindrical) bore hubs for flexible couplings.


AGMA Releases New Standard on Bevel and Hypoid Gear Geometry


The AGMA Technical Division is pleased to announce the publication of a new AGMA standard:

·         ANSI/AGMA ISO 23509-B17, Bevel and Hypoid Gear Geometry


This standard specifies the geometry of bevel gears. The term ‘bevel gears’ is used to mean straight, spiral, zerol bevel and hypoid gear designs. If the text pertains to one or more, but not all, of these, the specific forms are identified. This standard is intended for use by an experienced gear designer capable of selecting reasonable values for the factors based on his/her knowledge and background. It is not intended for use by the engineering public at large. ANSI/AGMA ISO 23509-B17 is identical to ISO 23509:2016.


NOTE: Electronic copies of these standards were made available to the AGMA technical representative at each member company via AGMA’s annual standards distribution email to members, which was sent out in late May 2018. Please contact this representative at your company for a PDF of these new standards. If you do not know who your company’s technical representative is, please contact Karina at
