S7005 CE/P4ADGA Bearing Product Overview & Core Advantages
The S7005 CE/P4ADGA is a high-precision double row angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. This sealed bearing is designed to accommodate combined loads (radial and bidirectional axial loads) simultaneously, making it an ideal solution for compact, high-performance assemblies. Its P4A tolerance class and universal matchable (SU) design ensure superior running accuracy and simplified mounting in preloaded arrangements. The pre-lubrication and sealing provide long-term, maintenance-free operation, establishing it as a reliable choice for demanding industrial environments.

| C | Specifies a 15° contact angle, optimized for high-speed operation and axial load capacity. |
| E | Indicates an optimized internal design for enhanced performance. |
| P4A | Signifies a high precision tolerance class, exceeding standard ABEC-7/ISO P4 levels for superior running accuracy. |
| DGA | Represents the universal matchable (SU) arrangement and extra light preload (Class A). |
S7005 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides a rigid support system, enabling the bearing to handle significant combined loads and bidirectional axial forces effectively. This robust construction ensures stable operation under demanding conditions.
High-Speed Performance: Featuring a lightweight and durable phenolic cage, this bearing achieves a high limiting speed of 83,000 rpm. The optimized internal geometry and 15° contact angle further contribute to its exceptional high-speed capabilities with minimal heat generation.
Precision & Longevity: Manufactured to P4A tolerance class with chrome steel rings and balls, this bearing guarantees precise shaft guidance and smooth operation. The integral seals retain the factory-applied grease lubrication, protecting against contamination and providing a long, maintenance-free service life within a temperature range of -30°C to 110°C.
