ANGULAR CONTACT BEARINGS
Single row angular contact ball bearings feature raceways with high and low shoulders. These
opposing raceways are designed to carry thrust load in one direction. The bearings in this series
are assembled with a specific internal clearance so that they will have a specified contact angle
under load. In electric motor applications the standard contact angle is 40 degrees. These
bearings feature a bronze cage and are flush ground for stacking.

Duplex mounted bearings use a set of two (or more) on a common shaft with the inner and
outer rings clamped solidly together. They are used to gain axial shaft control, rigidity and extra
capacity. There are three fundamental combinations in duplex bearings: face-to-face (DF),
back-to-back (DB), and tandem (DT).
