ISO 3030 pdf download Rolling bearings — Radial needle roller and cage assemblies — Boundary dimensions and tolerances
This International Standard specifies the boundary dimensions for radial needle roller and cage assemblies.
In addition, it gives the tolerances for the cage width and method of functional gauging of smallest single bore diameter of needle roller complement.
Informative values for the tolerances of shaft raceway, housing raceway and raceway widths are given in Annex A.
