Standard Specification for Rollers, Bearing, Needle, Ferrous, Solid

ABSTRACT
This specification covers the procurement requirements for solid ferrous needle rollers, including the MS19065 spherical ended solid ferrous needle rollers, intended for use in bearings and bearing applications. Rollers shall be made of chrome alloy steel E52100, and manufactured in any of the following types: Type I—spherical end; Type II—flat end; Type III—ball end; Type IV—crankpin end; Type V—conical end; and Type VI—trunnion end. Representative rollers shall be inspected by dimensional and visual examination, surface roughness examination, hot acid etch test, decarburization test, hardness test, chemical analysis, macro-examination, austenitic grain size test, and inclusion rating test.
SCOPE
1.1 This specification covers the procurement requirements for solid ferrous needle bearing rollers including the MS19065 spherical ended solid ferrous needle rollers as specified in Specification F2443.  
1.2 Intended Use—The rollers covered in this specification are intended for use in bearings and bearing applications.  
1.3 This specification contains many of the requirements of MIL-R-22440, 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
