Chamfer dimensions on the back face of the inner and outer rings of the bearing are larger than maximum values for installation dimensions ras and r1as.2. As for the maximum value for inner and outer ring diameters of bearings whose bearing numbers are marked with "†" (inner ring) and "††" (outer ring), the precisionclass is an integer for class 4 and class 2 bearings only.B-178
