7001 CEGA/HCP4A Bearing Product Overview & Core Advantages
The 7001 CEGA/HCP4A is a single-row angular contact ball bearing designed for ultra-high precision applications requiring exceptional rotational accuracy and speed capability. Manufactured to ABEC 7 / P4A tolerance class, this bearing delivers superior running accuracy and dimensional stability. Its ceramic balls and optimized 15° contact angle enable outstanding high-speed performance while providing excellent resistance to thermal expansion. The bearing comes pre-lubricated and is universally matchable (SU), allowing for precise axial preload adjustment when mounted in pairs.
