Technical Standards



The AGMA Helical Gear Rating Committee has started a new project to update the Information Sheet AGMA 925-A03, "Effect of Lubrication on Gear Surface Distress".

Currently, AGMA 925 gives methods for calculating elastohydrodynamic lubrication (EHL) film thickness and predicting the probability of wear, and methods for calculating the contact temperature and predicting the probability of scuffing.  As part of the revision project, the committee is planning to update these methods and wishes to develop a method for predicting the probability of micropitting.  Once completed, the committee plans to offer the new document for adoption by ISO Working Group on micropitting (WG 15).

To enhance its current broad acceptance within the industry, the committee aims to make the revision project a multi-disciplinary effort that includes people from the gear industry, lubrication industry, academic and industrial researchers in tribology, and anyone interested in the tribology of gear teeth.

If you are interested in taking part in this project, please contact Amir Aboutaleb, Vice President of AGMA Technical Division at or call 703-684-0211.


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.
