All Analytical Angular Contact Ball Bearings

---

Angular contact ball bearings are a type of rolling bearing designed to handle both radial and axial loads. Also known as radial thrust ball bearings, they offer high-speed capabilities similar to deep groove ball bearings but with greater rigidity. This is due to their ability to accommodate more steel balls, allowing for higher radial load capacity and the ability to support significant axial loads—either in one direction or as pure axial loads. These bearings are typically used in pairs, especially in applications requiring rigid double support systems, such as precision spindles or small span shafts, to enhance overall system stiffness. ### Layout Characteristics of Angular Contact Ball Bearings **Single Row Angular Contact Ball Bearings** These bearings can handle radial and unidirectional axial loads. The contact angle between the balls and the inner/outer rings is usually 15°, 25°, 30°, or 40°. The larger the contact angle, the greater the axial load capacity. In most cases, two single-row angular contact bearings are mounted in opposite directions, with internal clearance adjusted accordingly. **Paired Double Bearings** When two radial bearings are paired together, they form a double-bearing arrangement. These pairs are commonly made from the same type of angular contact ball bearings or tapered roller bearings. There are three main configurations: - **DF (Face-to-Face):** Accepts radial and axial loads in both directions. - **DB (Back-to-Back):** Also supports bidirectional axial and radial loads. - **DT (Stacked):** Designed for heavy axial loads in one direction only. **Double Row Angular Contact Ball Bearings** This design features two rows of balls within a single unit, with the inner and outer rings integrated. It allows for dual axial load capacity, making it ideal for applications requiring high rigidity and stability. ### Detailed Classification and Types 1.
