ASTM F2443-04(2012)

Standard Specification for Roller, Bearing, Needle, Ferrous, Solid, Spherical End

ABSTRACT
This specification covers spherical-ended ferrous needle rollers intended for use as bearing components. Rollers shall be made of chrome alloy steel E50100, E51100, E52100, and shall conform to specified requirements for heat treatment and protective coatings. Rollers shall also meet specified values for diameter, length, and effective length in accordance with MS Part No.
SCOPE
1.1 This specification covers ferrous needle rollers having spherical ends.  
1.2 Spherical-ended needle rollers designed to this specification are intended for use as bearing components. A complement of rollers is run on a hardened (HRC 58-65, see Test Methods E18) shaft and in a hardened (HRC 58-65) housing bore to form the bearing.  
1.3 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.  
1.4 This specification contains many of the requirements of MS19065, which was originally developed by the Department of Defense and maintained by the Defense Supply Center Richmond. The following government activity codes may be found in the Department of Defense, Standardization Directory SD-1.2
