ASME SRB-1-2018 (R2023)

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.
