Standard Specification for Bearing, Roller, Needle: Assembly (Thick Outer Race)
ABSTRACT
This specification covers needle roller bearing assemblies that have thick outer rings, cages, rollers and inner rings. The assemblies consist of a MS51961 thick outer race needle roller bearing as specified and a corresponding MS51962 inner ring as specified. The bearings are intended to be used on unhardened shafts. MS51961 bearings without inner rings may be used directly on hardened shafts. Bearings designed to this specification are intended for use in applications requiring high radial load with minimal angular shaft misalignment. Requirements such as heat treatment of bearing and inner rings, protective coating and lubrication are also discussed.
SCOPE
1.1 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
1.2 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).
1.3 Bearings designed to this specification are intended for use in applications requiring high radial load with minimal angular shaft misalignment.
1.4 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.
