Load Classification & Service Factors for Flexible Coupling
AGMA 922-A96 (reaffirmed May 2015)

SCOPE
The purpose of this information sheet is to list and classify the character of the load, and the suggested service factor for various applications, so that proper flexible coupling selection can be made for a given service.

APPLICABILITY
This information sheet is applicable to standard couplings as defined in AGMA 510.03.

EXCEPTIONS
It is recognized that there are couplings for which the service factor values shown in this information sheet are not necessarily applicable.  For specific application information, refer to the manufacturer’s catalog or recommendations.  AGMA acknowledges the right of any manufacturer to use different selection methods, or service factors, or both for their specific product.

FOREWORD
[The foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be construed as a part of AGMA 922-A96, Load Classification and Service Factors for Flexible Couplings.]

This document was developed originally as standard AGMA 514.01 by the Flexible Coupling Product Group of AGMA to show some of the applications for flexible couplings and to serve as a guide to the character of the loads found in these applications.  It made no attempt to include all possible applications for flexible couplings, but a sufficient number and variety were covered to serve as a guide for proper application.

The load classification and service factors shown in this document vary for some types of equipment from identical or similar equipment as shown in other AGMA Standards.  Such variations are not errors or discrepancies, but have been determined based on design, construction and limitations of the flexible coupling.

The first draft of AGMA 514.01 was prepared by the Flexible Coupling Technical Committee in January 1968.  It was approved by Flexible Coupling Product Group 7 on October 20, 1968.  AGMA 514.01 became an official AGMA standard on May 27, 1969.  AGMA 514.02 was a revision of AGMA 514.01.  The major change was the addition of Service Factors to table 2.  AGMA 514.02 was approved by the AGMA Membership on October 22, 1971.

The Flexible Couplings Committee voted to change the standard to an information sheet.  The only changes made were editorial, necessary to reflect an information sheet.

Suggestions for improvement of this standard will be welcome.  They should be sent to the American Gear Manufacturers Association, 1001 N. Fairfax Street, Suite 500, Alexandria, Virginia  22314.
