* The bearing type has raceways in both the inner and outer rings with a specific contact angle.
* These bearings cannot be separated.
* They can accommodate a larger number of balls compared to deep-groove ball bearings due to their counter-bore construction.
* The cage material can be pressed steel, high-strength brass, or synthetic resin, depending on the bearing series and service condition.
* Single-row angular contact ball bearings can handle radial, axial, or combined loads, but axial loads must be in one direction.
* These bearings are typically used in pairs to handle the induced load caused by the internal axial force from the applied radial load.
* NACHI provides preadjusted clearance for paired bearings when mounting two single bearings in adjacent positions.
* Paired combination bearings are matched sets.
* Combination bearings can be arranged in three configurations: back-to-back (DB), face-to-face (DF), or tandem (DT).
* DB or DF sets can handle bidirectional axial loads.
