7256BDF NSK ANGULAR CONTACT BALL BEARINGS

NSK Single-Row Angular Contact Ball Bearings
Since these bearings have a contact angle, they can sustain significant axial loads in
one direction together with radial loads. Because of their design, when a radial load is
applied, an axial force component is produced; therefore, two opposed bearings or a
combination of more than two must be used.

Double-Row Angular Contact Ball Bearings:

This is basically a back-to-back or face-to-face arrangement of two single-row angular

contact ball bearings, but their inner or outer rings are integrated into one. Axial loads

in both directions can be sustained, so these bearings are used as fixed-end bearings.

Cross-sections of double-row angular contact ball bearings are shown below. The

bearings in Figures 5 and 7 have good capacity to sustain moments.
