Alcance
ISO 1206:2018 specifies the boundary dimensions and normal class tolerance values for needle roller bearings with machined rings.ISO 1206:2018 specifies dimensional and geometrical characteristics, and limit deviations from nominal sizes.These specifications apply to complete needle roller bearings and to bearings without inner ring.Recommended values for the tolerances for shaft raceways for needle roller bearings without inner ring are given in Annex A.
