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 E 18). For use with unhardened shafts, bearings should be used in conjunction with inner bearing ring as specified in MS51962 shown as bearing assemblies in MS500072.
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 the standard. The values given in parentheses are provided for information only.
Note 1—This specification contains many of the requirements of MS 51961, which was originally developed and maintained by the Defense Supply Center Richmond.
