71815 CD/P4 Bearing Product Overview & Core Advantages
The 71815 CD/P4 is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. This metric bearing features a P4 (ABEC-7) tolerance class, ensuring minimal runout and superior performance in demanding operational environments. Its 15° contact angle is optimized to support significant combined loads—handling both radial and axial forces efficiently. The phenolic resin cage contributes to smooth operation at high speeds, while the preload availability enhances system stiffness, making it ideal for applications where high rigidity and positional accuracy are critical.
