7012 CE/P4BVG275 Bearing Product Overview & Core Advantages
The 7012 CE/P4BVG275 is a single-row angular contact ball bearing designed for applications requiring high precision and superior rotational accuracy. Manufactured to P4 (ABEC-7) tolerance class, this bearing delivers exceptional dimensional stability and running accuracy. Its key advantage lies in its ability to accommodate combined loads (radial and axial) simultaneously, making it ideal for high-speed spindles and precision machinery. The phenolic cage and optimized 15° contact angle contribute to its excellent high-speed performance and smooth operation.
