TAC ball bearing vs tapered roller bearings
TAC ball bearing vs tapered roller bearings
(OP)
Please educate me about double row angular contact (DAC) ball bearing hubs versus tapered roller (TR) bearing hubs. I am considering retrofittng a strut and TR hub combo from a previous model to a race car with DAC hubs. At first glance critical measurements seem OK, hub offset, etc
I was under the impression that DACs advantages are manufacturing simplicity and with setting preload, whereas tapered roller bearings are slightly better for axial loads but required 'old school' preload adjustment.

I've used ball and roller bearings in street, drag and, road race cars with few problems with any application. I've use DAC bearings, in two piece, one piece configuration and with either dual ball or dual roller bearings in industrial applications. Preload settings can and ofter are critical in any of these applications. Preload adjustment? Damn skippy!
If your having trouble with this concept, find someone to help that knows the "old school" method. Old school? Come on...

As such they are very much non adjustable.

RE: TAC ball bearing vs tapered roller bearings
For automotive application recently undertaken...I use non adjustable bearings for the Al hubs on my Mini, front and rear. They were supposed to be the HOT setup. Perhaps the reason I have not had problems with them (as most others have) is my willingness to modify the preload with shims, machine work, etc. Dunno. Had I to do them over, I would go back to OEM as these "modern" bearings seem no better than the "old school"!
This site is not where I ordered my Mini parts, but is pretty much the same type store.

But on a race car, no, can't see the point.
