Product Description:
"The connection between the ball ball and the contact point of the inner and outer ring of the contact ball bearing is in the radial angle. The contact angles are generally divided into 15 °, 30 °, and 40 °. They are represented by the letters C, A, and B, respectively. produces such bearings with a contact angle of 25 ° and is represented by A711.
Single row angular contact ball bearing can bear radial load and axial load in single direction. DB combination, DF combination into four point contact, double row angular contact ball bearing, can withstand radial and bidirectional axial load. Angular contact ball bearings are suitable for high speed and high precision rotation.
This kind of bearing is mainly used in machine tool spindle, high frequency motor, oil pump, air compressor, printing press, etc. Four point angular contact ball bearings are usually used in the oil roller box of rolling mill to bear axial load.

Angular contact bearings are a type of rolling element bearing specifically designed to handle both radial and axial loads. They are characterized by the angle at which the rolling elements make contact with the races, which allows them to accommodate axial loads in one direction. This essential feature makes angular contact bearings a popular choice across various industries, particularly in applications that require precise handling of combined loads and high-speed operations.
**Single-row Angular Contact Bearings**
Single-row angular contact bearings are constructed with one row of rolling elements, typically balls, positioned diagonally. They are designed to handle significant axial loads in one direction, along with radial loads. The contact angle, an essential feature of these bearings, defines their load-carrying capacity. A larger contact angle enhances the bearing’s ability to handle axial loads, while a smaller angle improves performance for higher speeds.
These bearings are often used in applications where space is at a premium, such as in automotive gearboxes, pumps, and machine tool spindles. They are usually mounted in pairs, either back-to-back or face-to-face, to effectively support axial loads in both directions, increase rigidity, and accommodate misalignment to some extent.
**Double-row Angular Contact Bearings**
Double-row angular contact bearings consist of two rows of rolling elements arranged back-to-back. This configuration allows them to support higher radial loads and axial loads in both directions compared to single-row designs. They offer a more compact solution than pairing two single-row bearings, which makes them advantageous in applications where space and weight are critical considerations.
These bearings find applications in areas such as the wheel hubs of vehicles, industrial machinery, and other equipment that demands robust performance under combined loads and moderate speeds. The double-row design also provides greater structural stability, which can contribute to a longer service life under demanding conditions.
Angular contact bearings, with their unique design and versatility, play a vital role in a wide range of engineering applications. Understanding the differences between single-row and double-row angular contact bearings is crucial for selecting the appropriate bearing for specific requirements. By considering factors such as load direction, speed, and space constraints, engineers can ensure optimal performance and longevity of systems utilizing these bearings."
