Bearing Inner Ring Tolerance. Radial runout of assembled bearing inner ring k ia single outer ring or inner ring width deviation. Technical info overview nomenclature materials cages retainers shields and seals ball bearings geometry. Form tolerances include the roundness taper runout parallelism and race radius of the raceway.
Bearing tolerances are standardized by classifying bearings into the following six classes accuracy in tolerances becomes higher in the order described. Deviation of a minimum circumscribed size of inner ring width between two opposite lines in any longitudinal section which includes the inner ring bore axis from its nominal size asymmetrical rings lower limit deviation of a two point size of inner ring width from its nominal size c nominal outer ring width nominal outer ring width.
Bearing tolerances refer to three aspects of accuracy.
The critical features of the rings include the bore or inner diameter of the inner ring the outer diameter of the outer ring the ring widths and the raceways of each ring.
