Product Information
The 7000 series angular contact ball bearings are mainly used in applications where speed and positioning accuracy are both important.
Compared with standard deep groove ball bearings, this series is better at handling combined radial and axial loads, especially in systems that run at higher speeds and require stable rotation.
In most real applications, these bearings are used in machine tool spindles, motors, pumps, and other precision transmission systems where vibration control and rigidity are important.

7900C/AC Angular Contact Bearing Product Feature:
25° Contact Angle
The 7900C/AC uses a 25° contact angle for an optimal balance of load and speed. It carries higher axial loads than 15° designs and outperforms 40° versions in high-speed applications.
Material & Manufacturing
We use high-purity GCr15 bearing steel from leading mills for maximum fatigue resistance.
Heat Treatment
Our automated process ensures consistent hardness (HRC 60-64) and a tough core.
Service Life
This combination results in an L10 life 15-20% longer than standard bearings.
