7002 ACD/P4A Bearing Product Overview & Core Advantages
The 7002 ACD/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 25° contact angle optimized for handling significant axial loads in one direction. Manufactured to P4 (ABEC-7) tolerance class, it delivers superior running accuracy and is preloaded for enhanced system stiffness and minimal axial/radial play, making it ideal for high-speed spindles and precision machinery.
