71816 CD/P4 Bearing Product Overview & Core Advantages
The 71816 CD/P4 is a single-row angular contact ball bearing designed for applications requiring high precision and superior running accuracy. Engineered to the P4 (ABEC-7) tolerance class, it offers exceptional dimensional stability and rotational precision. Its key advantage lies in its ability to accommodate combined loads, efficiently handling significant radial loads and axial loads in one direction simultaneously. The optimized 15° contact angle provides an excellent balance between axial load capacity and operational speed. With its phenolic resin cage and pre-lubrication, this bearing is built for high-speed performance and reliable operation in demanding environments.
