7009 CD/P4A Bearing Product Overview & Core Advantages
The 7009 CD/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 (radial and axial) in one direction, its 15° contact angle provides optimal axial load capacity. Manufactured to P4 (ABEC-7) tolerance class, it ensures minimal runout and vibration, making it ideal for high-speed spindles and precision machinery. The phenolic cage and preloaded configuration contribute to its high rigidity and stable performance under demanding conditions.
