AMERICAN BEARING MANUFACTURERS ASSOCIATION The American Bearing Manufacturers Association (ABMA) is comprised of the most successful and forward-thinking manufacturers in the U.S. bearing industry. Formerly the Anti-Friction Bearing Manufacturers Association (AFBMA), the ABMA was formed in 1917 as an informal committee to aid the U.S. production of bearings in World War I. Continuing that tradition, the ABMA has become the collective voice of the American bearing industry, influencing government policies and international trade. ABMA has developed more than 25 industry standards addressing insert bearings, tapered roller bearings, miniature/instrument bearings, linear motion bearings and more.
