7213 CD/P4A Bearing Product Overview & Core Advantages
The 7213 CD/P4A is a single-row angular contact ball bearing designed for applications requiring high precision and superior running accuracy. Engineered to a P4 (ABEC-7) tolerance class, it excels in handling combined radial and axial loads simultaneously. Its 15° contact angle is optimized for high-speed operation, while the phenolic resin cage ensures stability and reduced friction. This bearing is preloaded from the factory, providing immediate high rigidity and precise shaft positioning, making it ideal for demanding, high-accuracy machinery.
