7201 CDGB/P4A Bearing Product Overview & Core Advantages
The 7201 CDGB/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, it delivers superior dimensional stability and running accuracy. Its 15° contact angle is optimized to support combined loads (radial and axial) simultaneously, while the Universal Matchable (SU) design allows for flexible mounting in duplex arrangements. Pre-loaded with Light / Class B preload, this bearing ensures minimal deflection and vibration, making it ideal for high-speed spindles and precision machinery.
