Choose SKF bearings precision class

   SKF bearing tolerance level from 0 level up in turn for improving, for general purpose 0 level has enough, but used in table 1 shows condition or situation, need 5 level or higher precision. The precision of the above level based on ISO standard though set, but the call in the national standards in different.

    The list of bearing type of applicable SKF precision grades and a comparison between national standards. Size accuracy (and shaft and shell installation related projects) 1, diameter, outer diameter, width and assembly of the width of the allowable deviation 2, the roller in the group and the diameter months-moons months-moons diameter deviation 3, but the size of the Angle limit value allowed 4, width of the amount allowed changes Rotation precision (and beat the area related projects) 1, inner ring and outer ring the permission of the axial and radial beat beat 2, the permission of the inner circle transverse pumping 3, outer diameter gradient allows variations under surface 4, thrust bearing groove thickness changes allow amount The size of the standard SKF bearing many forms, in mechanical design of the device when had better use the standard bearing (this design to bearing it is easier to purchase in here, said a infrastructures, some bearing on the catalog SKF model does, but some non-standard bearings in mainland China, sometimes not spot the futures will be a long time, so in bearing model selection to consider
