1) The dimension b a is measured from the centre of the housing seat. There are two special cases:
1 For self-aligning ball bearings in the 12 series, values in brackets are suitable.
2 For non-locating bearing arrangements, and in particular for the widest bearings, the values for b a must
be adj usted if the bearing is not centered in the housing seat.
