71952 ACD/P4ADGA Bearing Product Overview & Core Advantages
The 71952 ACD/P4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This universal matchable (SU) bearing features a P4A tolerance class and extra light preload (Class A), making it ideal for high-speed spindles and precision machinery. Its 25° contact angle enables it to handle combined radial and axial loads simultaneously, while the phenolic cage ensures stable operation at limiting speeds up to 4,500 rpm.
