AC5640B KOYO Angular Contact Ball Bearings

KOYO  angular contact ball bearings.

Single-row bearings can accommodate radial load and axial load in one direction.

DB and DF matched pair bearings and double-row bearings can accommodate radial load and axial load in both directions.

Two or more single-row angular contact ball bearings are often combined in order to increase the load rating or rigidity. In this case, two types of arrangements, back-to-back

arrangement (DB) and face-to-face arrangement (DF), are available. If the load rating of a single-row angular contact ball bearing is insufficient, use the tandem arrangement (DT).
