S7006 CEGA/P4A Bearing Product Overview & Core Advantages
The S7006 CEGA/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered to the exacting P4A tolerance class, this bearing is capable of simultaneously supporting combined loads (radial and axial) in high-speed environments. Its compact design, featuring a phenolic cage and extra light preload (Class A), ensures smooth operation, minimal heat generation, and high running accuracy, making it ideal for high-precision spindles and other critical machinery.
S7006 CEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CEGA | Specific internal design and clearance for universal matching. | Enables precise bearing arrangement when mounted with a second, universally matchable bearing. |
| P4A | High-Precision Tolerance Class. | Guarantees extremely tight dimensional and running accuracy for superior performance in demanding applications. |
S7006 CEGA/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4A tolerance standards with an extra light preload, this bearing provides exceptional rotational accuracy and system rigidity, minimizing deflection under load.
- Optimized for Combined Loads: The 15° contact angle is engineered to efficiently handle combined radial and axial loads, a common requirement in precision machinery.
- High-Speed Capability: The lightweight and robust phenolic cage ensures stability and low friction at the high limiting speed of 100,500 rpm, reducing centrifugal forces and heat buildup.
- Sealed & Pre-Lubricated: As a sealed bearing with factory-applied grease lubrication, it is protected from contamination and offers long-term, maintenance-free operation within its specified temperature range.
S7006 CEGA/P4A Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding)
