Bearing tolerance includes dimensional tolerance and revolving tolerance,Dimensional tolerance is a request when bearings are mounted on shafts or in housings.It includes bore/outerside diameter deviation from basic,inner ring/outer ring width deviation from basic and radius allowance.Geometric tolerance includes bore/outside diameter deviation in single planne,inner ring/outer ring width deviation in single radial plane.Revolving tolerance includes radial and axial runout of assembled bearing inner ring and outer ring,inner ring reference fcace runout with bore and outside cylindrical surface runout with outer reference face.
