7010 ACD/P4A Bearing Product Overview & Core Advantages
The 7010 ACD/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to support combined loads (radial and axial loads in one direction), this bearing features a 25° contact angle for optimal axial load capacity. Manufactured to P4 (ABEC-7) tolerance class, it delivers superior running accuracy, making it ideal for machine tool spindles and other high-speed, high-rigidity applications. Its phenolic cage and prelubrication contribute to smooth operation at limiting speeds up to 24,000 rpm.
