Scope
This standard specifies the dimensional tolerances of centripetal needle roller and cage assemblies. In addition, it also stipulates the functional testing methods for the width tolerances of cages and the minimum single inner diameter of needle rollers. The recommended tolerances for shaft raceways, housing raceways, and raceway widths are provided in Appendix A.
