2、ion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers needle roller bearin
3、g assem-blies. These assemblies have thick outer rings, cages, rollers,and inner rings. The assemblies consist of a MS51961 thickouter race needle roller bearing as specified in SpecificationF 2246 and a corresponding MS51962 inner ring as specified inSpecification F 24311.2 The bearings being speci
4、fied are intended to be used onunhardened shafts. MS51961 bearings without inner rings, asspecified in Specification F 2246, may be used for used directlyon hardened shafts (HRC5865; see Test Methods E18).1.3 Bearings designed to this specification are intended foruse in applications requiring high
