ABMA: American Bearing Manufacturers Association
ABMA, the American Bearing Manufacturers Association, is a nonprofit organization that develops and publishes standards for all aspects of the bearing industry. Headquartered in Washington, D.C., United States, ABMA standards are used throughout the United States and, through its 28 member companies, represent approximately 80% of all American bearing production. ABMA also serves as the administrator for the U.S. TAGs (United States Technical Advisory Group) to ISO/TC 4 (International Organization for Standardization/Technical Committee) and to all of its subcommittees. Standards from ABMA-bearing are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: [email protected] or 1-212-642-4980 or Request Proposal Price.
Below are ABMA-bearing's best-selling standards. To find additional standards, please use the search bar above.
ANSI/ABMA 8.2-2023
Rolling Element Bearings – Shaft Mounted – Locknuts, Sleeves, and Locking Devices – Inch Desig
There are many methods to mount Rolling Element Bearings, REB. This Standard provides attributes of inch nominal mounting accessories used for locating or fixing REB to the shaft. The purpose of the standard is to establish dimensions and minimum physical properties of these components consistent and compatible with ABMA, ANSI, and ISO Standards relating to ball and roller bearings. Products manufactured in accordance with this standard will fulfill the expected function when used with properly-designed shafts.

Load Ratings and Fatigue Life for Ball Bearings
Ball bearing performance is a function of many variables. These include the bearing design, the characteristics of the material from which the bearings are made, the way in which they are manufactured, as well as many variables associated with their application. The only sure way to establish the satisfactory operation of a bearing selected for a specific application is by actual performance in the application. As this is often impractical, another basis is required to estimate the suitability of a particular bearing for a given application. This is the purpose of this standard. This standard specifies the method of calculating the basic dynamic load rating of rolling bearings within the size ranges shown in the relevant ANSI/ABMA standards, manufactured from contemporary, commonly used, good quality hardened bearing steel in accordance with good manufacturing practice and basically of conventional design as regards the shape of rolling contact surfaces. This standard also specifies the method of calculating the basic rating life, which is the life associated with 90% reliability, with commonly used high quality material, good manufacturing quality and with conventional operating conditions. In addition, it specifies the method of calculating adjusted rating life, in which various reliabilities, special bearing properties and specific operating conditions are taken into account by means of life adjustment factors. Furthermore, this standard specifies the method of calculating the basic static load rating and the static equivalent load for ball bearings within the size ranges shown in the relevant ANSI/ABMA Standards, manufactured from good quality hardened bearing steel, in accordance with good manufacturing practice and basically of conventional design as regards the shape of rolling contact surfaces.

Tapered Roller Bearings - Radial Inch Design
This standard covers inch design radial tapered roller bearings of various types, part numbering systems, boundary dimensions, tolerances, and fitting practices. Tapered roller thrust bearings are covered in a separate ABMA standard. General ABMA standards which apply to various types of bearings should be consulted for tolerance definitions, gauging practices, mounting accessories, and method of evaluating load ratings.

ANSI/ABMA 20:2011 (R2020)
Radial Bearings of Ball, Cylindrical Roller and Spherical Roller Types - Metric Design
This standard includes: (a) basic plan for the boundary dimensions of metric radial ball and roller bearings; (b) general rules for extension of the basic plans; (c) dimensions and tolerances for snap ring groove and locating snap rings; (d) dimensions for radial ball bearings with flanged outer ring; and (e) tolerances for boundary dimensions, chamfers, various runouts and internal clearance. This standard does not contain any direction pertaining to internal bearing design nor any indication as to availability of bearings. Airframe bearings, instrument ball bearings, needle roller bearings, tapered roller bearings, thrust bearings and other bearing types and series not conforming to these basic plans for boundary dimensions are covered in other ANSI/ABMA Standards.
