7005 ACE/P4A Bearing Product Overview & Core Advantages
The 7005 ACE/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Designed to accommodate combined loads—handling significant radial loads alongside unidirectional axial loads—this bearing features a 25° contact angle for optimal axial load capacity. Manufactured to P4 (ABEC-7) tolerance class, it delivers superior running precision and is preloaded for enhanced system stiffness. Its phenolic resin cage and specialized lubrication enable reliable performance in demanding, high-speed environments up to 63,000 rpm.
