Setting the Standard for Power Transmission Manufacturing
The Motion + Power Manufacturers Alliance (MPMA) runs standards development for power transmission manufacturing. ABMA and AGMA have set national bearing and gearing standards since the early 1900’s, and MPMA continues that work.
MPMA serves as the focal point within the United States for the development of ISO bearing and gearing standards. MPMA serves the international gearing community as the Secretariat of ISO TC 60 – Gears, helping to manage international gearing standardization in that role. MPMA also participates on ISO TC 4 – Rolling bearings to help bring the US position on the global bearings standards platform.
Standards development spans critical areas including:
- Gear and bearing design and analysis
- Materials, metallurgy, and heat treatment
- Manufacturing processes and quality control
- Performance, lubrication, and efficiency
- Inspection, testing, and failure analysis
Through this collaborative framework, MPMA maintains a trusted foundation for technical excellence across the power transmission industry.
Access Technical Standards and Publications
MPMA maintains a comprehensive library of technical standards, engineering information sheets, and reference materials supporting the power transmission industry.
All ABMA or AGMA published standards and information sheets are up-to-date and listed in our Technical Publications Catalog. It offers an exclusive list of outdated standards and their modern counterparts, and is revised as new products become available. The date of the last revision always appears on the first page.

Participate in the Standards Development Process
MPMA standards evolve through active industry participation. Members contribute technical expertise, monitor standards development, and help guide the requirements that shape mechanical power transmission manufacturing.
Participation offers valuable insight into emerging technologies and provides companies with a direct voice in the standards that guide the market.
