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.

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.
