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.

  • Design Manual for Enclosed Epicyclic Gear Drives - This standard is a design manual for drives employing epicyclic gear arrangements. It includes descriptions of epicyclic drives, nomenclature, application information and design guidelines with reference to other AGMA standards. This standard is applicable to enclosed epicyclic speed reducers and increasers which use spur and helical gears. This new standard replaces ANSI/AGMA 6123-B06 
  • ISO 6336-5:2016 - 09-29-16
    Calculation of load capacity of spur and helical gears Part 5: Strength and quality of materials - 

    This standard describes contact and tooth-root stresses and gives numerical values for both limit stress numbers. It specifies requirements for material quality and heat treatment and comments on their influences on both limit stress numbers.

    This new standard replaces ISO 6336-5:2003 
  • ANSI/AGMA 2002-C16 - 06-08-16
    Tooth Thickness and Backlash Measurement of Cylindrical Involute Gearing

    This standard establishes the procedures for determining the specification limits for tooth thickness of external and internal cylindrical involute gearing. It includes equations and calculation procedures for the commonly used measuring methods. A specific tooth thickness specification limit can be established from the design thickness or from another tooth thickness measurement. The procedures can be used with an established design tooth thickness, or with actual tooth thickness dimensions. The effect of tooth geometric quality variations on tooth thickness dimensions is discussed. Calculations for backlash are included, and are based on the specified tooth thickness, center distance, and tolerances.

    Flexible Couplings - Basis for Rating

    This standard presents criteria and guidelines for the establishment of the basis for ratings of standard flexible couplings. Due to the diversity of coupling types, details of design such as formulas and analysis used to derive the stresses, etc. are often considered proprietary and are not considered in this standard. This standard is of importance to coupling manufacturers, users and equipment designers for the proper selection, comparison and application of flexible couplings.
