Description of ASTM-F2430 2012ASTM F2430 - 04(2012)Standard Specification for Bearing, Roller, Needle: Assembly (Thick Outer Race)Active Standard ASTM F2430 | Developed by Subcommittee: F34.04 Book of Standards Volume: 01.08 ASTM F2430Abstract 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. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. 1. 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 (HRC5865; 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. The following government activity codes may be found in the Department of Defense, Standardization Directory SD-1. 2
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.
