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 adjusted if the bearing is not centred in the housing seat.
