【国外标准】 Standard Specification for Ring, Bearing, Inner: for Needle Roller Bearing With Drawn Outer Ring

This specification covers inner rings for needle roller bearings with drawn outer rings. The use of recycled materials that meet the requirements of the applicable material specification without jeopardizing the intended use of the item is encouraged. Bearing inner rings shall be manufactured of steel, alloy or carbon. The raceway (outside diameter) surface shall have a maximum surface roughness conforming to the requirements specified.1.1 This specification covers inner rings for needle roller bearings with drawn outer rings.1.2 The inner rings specified in this specification are intended for use on unhardened shafts in conjunction with open end needle roller bearings shown on Specification F2162 and MS52141.1.3 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 The inner rings specified in this specification are not intended for use in flight-critical systems of aircraft.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 1: This specification contains many of the requirements of MS17130, which was originally developed by the Department of Defense and is currently maintained by the Defense Supply Center Richmond.
