The Inch values shown in the table are conversion from the mertic values per ISO 286. you should expect about 0.1-0.5 thous errors wehn comparing with ANSI B4.1/4.2! The posision of H relative to the other Shaft deviations.

The following Engineering calculator will show the plus and minus tolerance for the specific ISO 286 Shaft tolerance data. Enter your desired preferred tolerance grade and the nomial size. Also see Table of Hole Tolerances per. ISO 286

Preferred fits and tolerance table for hole and shaft basis systems which are given in ISO 286-1 (2010) and ANSI B4.2-1978 standards. The usage of these tolerances is advised for economic reasons. Loose running fit for wide commercial tolerances or allowances on external members.

For a schematic representation of the most common rolling bearing fits. The tables as below contain recommendations for the selection of shaft and housing tolerances that are valid for normal fitting and operating conditions.
