contact ball bearings or tapered roller bearings. Possible combinations include face-to-face, which have the outer ring faces together (type DF), back-to-back (type DB), or both front faces in the same direction (type DT). DF and DB duplex bearings are capable of taking radial loads and axial loads in either direction. Type DT

However, the DT bearing set cannot be preloaded. The amount of preload can be adjusted by changing clearance between bearings, da0, as shown in Figs. 3 to 5. Preloads are divided into four graduated classification — Extra light (EL),. Light (L), Medium (M), and Heavy (H). Therefore, DB and DF bearing sets are often.

Compared with the DB Type, the distance between the effective load centers is small, so the capacity to sustain moments is inferior to the DB Type. Tandem (DT) (Example) 7208 A DT. Radial loads and axial loads in one direction can be sustained. Since two bearings share the axial load, this arrangement is used when the
