    1. Scope

    1.1 This specification covers needle roller bearings having thick outer rings, with rollers and cages.

    1.2 The bearings being specified are intended to be used with hardened shafts (HRC58-65; see Test Methods E18). For use with unhardened shafts, bearings should be used in conjunction with inner bearing ring MS51962 as specified in Specification F2431 and shown as MS500072 bearing assemblies in Specification F2430.

    1.3 The use of recycled materials that meet the requirements of the applicable material specification without jeopardizing the intended use of the item is encouraged.

    1.4 Bearings designed to this specification are intended for use in applications requiring high radial load with minimal angular shaft misalignment.

    1.5 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.

    Note 1This specification contains many of the requirements of MS51961 which was originally developed by the Department of Defense and maintained by the Defense Supply Center Richmond.
