AC Series

7318AC-AC Series

AC Series Angular Contact Ball Bearings are high-precision components designed to handle combined radial and axial loads simultaneously. Characterized by a defined contact angle (typically 25° or 30°), they excel in high-speed and high-rigidity applications. Their separable design allows for versatile paired mounting configurations like back-to-back or face-to-face, enabling optimized preload and moment capacity. These bearings are the preferred choice for machine tool spindles, robotics, and other demanding industrial machinery where precision, speed, and reliability are critical.
