7006 CB/P4A Bearing Product Overview & Core Advantages
The 7006 CB/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to withstand combined loads (simultaneous radial and axial loads), this bearing features a 15° contact angle optimized for axial load capacity. Its P4 (ABEC-7) tolerance class ensures minimal runout and vibration, making it ideal for high-speed operation up to 56,000 rpm. The phenolic cage and precision-ground chrome steel components deliver reliable performance in demanding industrial environments.
