Preload affects performance of ACBBs in much the same way that the contact angle does. As preload increases, the rigidity increases but the speed capability decreases.

Since the distance of the load centers of DB bearing set is longer than that of DF bearing set, they are widely. Figure, Arrangement, Features. Backtoback (DB) (Example) 7208 A DB. Radial loads and axial loads in both directions can be sustained. Since the distance between the effective load centers a0 is big, this type is suitable if moments are applied.
