S7000 ACD/P4A Bearing Product Overview & Core Advantages
The S7000 ACD/P4A is a single-row angular contact ball bearing engineered for applications demanding high precision and superior rotational accuracy. Its defining feature is the 25° contact angle, which enables it to support significant combined loads—both radial and axial loads in one direction. Manufactured to P4 (ABEC-7) tolerance class, this bearing offers exceptional dimensional stability and running accuracy, making it ideal for high-speed spindles and precision machinery. The bearing comes preloaded and lubricated from the factory, ensuring immediate operational readiness and consistent performance.
