This Standard applies to the design, application, installation, inspection requirements, and maintenance of slewing ring bearings (SRBs) using balls that do not require dynamic capacity-life ratings. These also may be called slewing rings. This is inclusive of four-point contact single-row and double-row ball bearings. Such bearings are used in, but not limited to, equipment such as hydraulic shovels, excavators, aerial platforms (manlifts), cranes, wind-power generators, building maintenance units (BMUs), and other equipment where one part of the structure must rotate with respect to another in an oscillating or indexing manner.

The purpose of this Standard is to define standard methods to evaluate variables and establish practices for satisfactory performance in ball SRBs in oscillating or indexing applications. This will allow effective communication and exchange of data among the user, installer, and SRB manufacturer such that all parties understand each other's requirements and have a common point of reference.

Certain parameters are standardized to reduce the potential for confusion between the SRB manufacturer and the user. Acceptance criteria and guidelines are provided for SRB design, material, inspection requirements, and application.
