ABS bearings are 3mm thicker than the non-ABS bearing. That extra 3mm holds whatever it is that the ABS sensor ring monitors. It may contain magnets, or it may contain ferrous elements that interact with the ABS sensor ring that fits on the axle. I just don't know. I wish someone that does know would chime-in on how the sampling of the HD ABS system works. I read somewhere where it is not even close to the number of samples taken by the BMW ABS system when determining when to activate ABS.
By the way, the last ABS bearing I purchased had an orange grease seal and it was made in Canada. Pic below with ABS on the left:

Doesn't the orange side face the sensor?
