Single row angular contact ball bearing

What are the main technical features of Single Row Angular Contact Ball Bearing

1. One of the distinctive features of single row angular contact ball bearings is their contact angle design. The contact angle refers to the angle between the contact line between the steel ball and the inner and outer ring raceways and the bearing axis. Common contact angles are 15°, 25° and 40°, etc. Different contact angles are suitable for different load conditions. The increase in contact angle can improve the axial load-bearing capacity of the bearing, but it will also increase friction and heat. Choosing the appropriate contact angle according to the specific application scenario is the key to ensuring bearing performance.

2. Another important technical feature of single row angular contact ball bearings is its four-point contact design. During the operation of the bearing, each steel ball contacts the inner and outer ring raceways at four points. This design can ensure that the bearing Higher stability under radial and axial loads. At the same time, the four-point contact can also effectively reduce stress concentration caused by installation errors or bearing deformation, thereby extending the service life of the bearing. High-precision processing technology is also one of the important features of single-row angular contact ball bearings. Through advanced processing equipment and technology, the dimensional accuracy, shape accuracy and position accuracy of the bearings can be ensured to reach an extremely high level, thereby meeting the needs of high-speed, high-precision transmission systems requirements.

3. Since single row angular contact ball bearings will produce internal axial components when subjected to pure radial loads, they usually need to be installed in pairs. Bearings installed in pairs are available in back-to-back configuration (DB), face-to-face configuration (DF) and tandem configuration (DT). When installing in pairs, it is also necessary to apply appropriate preloading force according to the specific application scenario to eliminate the clearance inside the bearing and improve the rigidity and operating accuracy of the bearing. The preloading force can be applied by adjusting the bearing seat or bearing cover. thickness, using wave springs or disc springs, etc.

3. Single row angular contact ball bearings will generate a large amount of heat when running at high speed. All heat dissipation properties are also one of its important technical features. In order to improve the heat dissipation performance of the bearings, oil lubrication or grease lubrication is usually used. Oil lubrication can be achieved through circulation. The oil takes away the heat inside the bearing and lowers the temperature of the bearing. Grease lubrication can reduce friction and heat by selecting high-performance grease. In the design of the bearing, structures such as heat dissipation holes and heat dissipation grooves will also be considered to increase the heat dissipation area and improve heat dissipation efficiency.

4. In the design and manufacturing process of single row angular contact ball bearings, attention is paid to improving durability and reliability. By selecting high-quality materials, optimizing structural design, improving processing accuracy and strict quality control, we can ensure that the bearings can still maintain stable performance in harsh working environments. At the same time, you also need to pay attention to correct installation, lubrication and maintenance methods during use to extend the service life of the bearings.
