Standard Specification for Bearing, Roller, Needle: Assembly (Thick Outer Race)
|Publication Date:||1 October 2004|
|ICS Code (Rolling bearings):||21.100.20|
This specification covers needle roller bearing assemblies. These assemblies have thick outer rings, cages, rollers, and inner rings. The assemblies consist of a MS51961 thick outer race needle roller bearing as specified in Specification F2246 and a corresponding MS51962 inner ring as specified in Specification F2431
The bearings being specified are intended to be used on unhardened shafts. MS51961 bearings without inner rings, as specified in Specification F2246, may be used for used directly on hardened shafts (HRC58-65; see Test Methods E18).
Bearings designed to this specification are intended for use in applications requiring high radial load with minimal angular shaft misalignment.
This specification contains many of the requirements of MS500072, which was originally developed by the Department of Defense and maintained by the Defense Supply Center in Richmond. The following government activity codes may be found in the Department of Defense, Standardization Directory SD-1.2
The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
