7005 CEGA/P4A Bearing Product Overview & Core Advantages
The 7005 CEGA/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior running precision. Its 15° contact angle and Extra Light (A) preload configuration make it ideally suited for handling combined radial and axial loads simultaneously, providing high system stiffness and minimal deflection. The phenolic cage and universal matching (SU) capability enable optimal performance in high-speed, high-reliability scenarios such as precision spindles.

| P4A | High precision tolerance class exceeding ABEC 7 standards |
7005 CEGA/P4A Bearing Structural Features & Performance Benefits
High Precision & Rigidity: The P4A tolerance class ensures minimal runout and vibration, while the 15° contact angle and Extra Light preload provide superior system stiffness against complex loading conditions.
High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, enabling stable operation at limiting speeds up to 85,000 rpm. The optimized internal geometry minimizes friction and heat generation.
Universal Matching Design: As a Universal Matchable (SU) bearing, the 7005 CEGA/P4A can be universally paired with another identical bearing in various preload configurations (DB, DF, DT), offering exceptional flexibility in mounting arrangements.
Superior Load Capacity: With a dynamic load rating of 1872 lbf and static load rating of 934 lbf, this bearing reliably handles significant combined radial and axial loads.
