Figure, Arrangement, Features. Back-to-back (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. Face-to-face (DF) (Example) 7208 B DF. Radial loads and axial loads in both.DF and DB duplex bearings are capable of taking radial loads and axial loads in either direction. Type DT is used when there is a strong axial load in one direction and it is necessary to impose the load equally on each bearing. Duplex Bearings. Double-row angular contact ball bearings are basically two single-row angular
