1. Contact angle optimization:
The biggest difference between Angular Contact Ball Bearings and traditional deep groove ball bearings is their designed contact angle. Angular contact ball bearings are designed so that the rolling elements (usually balls) roll at an oblique angle inside the bearing. This oblique contact can significantly reduce the contact area, thereby reducing friction and rolling resistance. Generally speaking, the contact angle of angular contact ball bearings is usually 15 degrees or 30 degrees, depending on its design purpose and application scenario. Smaller contact angles provide higher rotational speeds and lower friction losses, which are critical for applications requiring high-speed rotation and high performance.

2. Optimized ball shape and material:
The rolling elements (balls) of angular contact ball bearings are usually made of high-quality steel or ceramics. These materials have excellent mechanical properties and surface finish, allowing them to maintain stable operation during high-speed rotation. Precise machining and heat treatment ensure the geometry and surface quality of the ball, reducing energy loss and vibration during rolling while extending the service life of the bearing.

3. High-precision inner and outer ring design:
In order to adapt to the requirements of high-speed rotation, the inner and outer rings of angular contact ball bearings usually use high-precision processing technology and materials. These designs not only improve the bearing capacity and rigidity, but also reduce internal friction losses. High-precision machining ensures the geometric accuracy and surface flatness of the bearing during operation, further optimizing its performance during high-speed operation.

4. Proper lubrication and sealing:
High-speed rotating angular contact ball bearings require good lubrication and effective sealing measures to reduce friction, wear and the entry of contaminants. Appropriate selection of special grease or grease for high-speed bearings to ensure stable lubrication during high-speed rotation is one of the key factors to ensure long-term operation of the bearings. At the same time, effective sealing design can prevent external dust, moisture and chemicals from entering the inside of the bearing, thereby extending its service life and performance stability.
