A BSN series. A double row, angular contact thrust ball bearing in a back-to-back (DB) arrangement with a single outer ring. Already filled with high-performance grease, operation is easy. Lubrication holes allow for relubrication as required. The contact type seal has excellent seal performance, while minimizing effects on.Total Quality by NSK: The synergies of our global network of NSK Technology Centres. Just one example .

DBD, DFD.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.of the bearing.
