Description of ASTM-F2431 2012ASTM F2431 - 04(2012)Standard Specification for Ring Bearing, Inner: For Needle Roller Bearing with Thick Outer RingActive Standard ASTM F2431 | Developed by Subcommittee: F34.04 Book of Standards Volume: 01.08 ASTM F2431Abstract This specification covers inner rings for needle roller bearings having thick outer rings. The inner rings being specified are intended for use on unhardened shafts. Inner rings designed to this specification are intended for use in applications requiring high radial load with minimal angular shaft misalignment. Heat treatment and protective coating of the material shall meet the specified requirements. 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 inner rings for needle roller bearings having thick outer rings. 1.2 The inner rings being specified are intended for use on unhardened shafts in conjunction with the MS51961 needle roller bearings specified in Specification F2246 . 1.2.1 For needle roller bearings with thin outer rings (Specification F2162 , MS17131, MS52141) use inner rings specified in Specification F2163 . 1.3 Inner rings designed to this specification are intended for use in applications requiring high radial load with minimal angular shaft misalignment. 1.4 The values stated in inch-pound units are to be regarded as standard.
