Deep groove ball bearings are among the most commonly used types of rolling bearings. They are capable of handling both radial and bidirectional axial loads, making them ideal for high-speed applications with low noise and minimal vibration. These bearings often come with a steel dust cover or rubber seal and are pre-lubricated with extra grease. Some models feature an outer ring with a snap ring or flange, allowing for simple axial positioning and easier installation within machinery. The design of deep groove ball bearings includes a filling groove on the outer ring, which allows for more balls to be incorporated, thereby increasing the load capacity. The cages used in these bearings can be made from various materials such as stamped steel (wave-shaped, crown-shaped, S-shaped), copper alloys, phenolic resin, or molded plastic, depending on the application requirements. **Primary Applications:** - Automobiles: Rear wheels, transmissions, and electrical components. - Electrical Equipment: General-purpose motors and household appliances. - Industrial Machinery: Construction equipment, rail vehicles, agricultural machinery, and other industrial systems. Angular contact ball bearings have a specific contact angle between the raceway and the balls, typically 15°, 30°, or 40°. A larger contact angle increases the axial load capacity, while a smaller angle improves high-speed performance. Single-row angular contact bearings can handle radial and unidirectional axial loads, while double-row bearings can manage radial and bidirectional axial loads. When combined (DB, DF, DT), they offer even greater flexibility in load distribution. These bearings are commonly used in high-speed and high-precision applications such as machine tool spindles, gas turbines, and centrifugal separators. They are also used in small car front wheels and differential pinion shafts. The cage types include stamped steel (bowl-shaped, S-shaped, crown-shaped) and machined cages made from copper alloys or phenolic resin. Four-point contact ball bearings are designed to support both radial and bidirectional axial loads. They can replace angular contact bearings in certain configurations and are particularly suitable for applications involving pure axial loads or mixed axial and radial loads. Their unique design ensures that the balls maintain contact with the raceways regardless of the direction of the applied load. **Primary Applications:** - Aircraft jet engines - Gas turbines Self-aligning ball bearings feature a spherical outer ring raceway, allowing the bearing to adjust for misalignment caused by shaft deflection or housing issues. This self-aligning capability makes them ideal for applications where perfect alignment is difficult to achieve. Bearings with tapered bores can be easily mounted using a locking device on the shaft. Cage designs for self-aligning bearings include daisy-shaped, sunflower-shaped, and other specialized forms. These bearings are widely used in woodworking and textile machinery, as well as in vertical shaft applications.
