As a result, NSK's precision bearings are also used in a wide variety of industries, the products to customers without delay. NSK also provides technical support globally to help customers determine the best bearing for each application and Bearings can be configured in the usual arrangements of DB/DF/DT, as.
By selecting the DB or DF bearing sets with the proper preloads which have already been adjusted to an appropriate range by the bearing manufacturer, the radial and axial displacements of the bearing inner and outer ring can be reduced as much as allowed by certain limits. However, the DT bearing set cannot be.
Usually, the cages for angular contact ball bearings with a contact angle expected, please consult with NSK for selection of the bearings. . ANGULAR CONTACT BALL BEARINGS. SINGLE/MATCHED MOUNTINGS. Bore Diameter 10 – 15 mm. 7900 A5 DB DF DT. 4 700. 2 900. 475. 296 32 000 43 000 13.5. 1.5. —.
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
