S7002 CEGA/P4A Bearing Product Overview & Core Advantages
The S7002 CEGA/P4A is a super-precision double row angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. Positioned in the P4A tolerance class, it guarantees ultra-tight dimensional and running accuracy. Its double row design enables it to support substantial combined loads—simultaneously handling radial loads and bidirectional axial loads. This makes it an ideal, compact solution for high-speed spindles and other high-precision machinery where reliability and performance are critical.
S7002 CEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Universal Matchable bearing designed to be mounted in a back-to-back (DB) arrangement. |
| GA | Indicates a specific internal clearance and preload level. In this case, Extra light preload (Class A). |
| P4A | Denotes a super-precision tolerance class exceeding ABEC 7 standards, ensuring minimal runout and vibration for superior performance. |
S7002 CEGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The double row angular contact structure and a 15° contact angle provide high rigidity, enabling the bearing to withstand significant combined radial and axial loads from both directions.
- Super-Precision Performance: Manufactured to P4A tolerance class with a bore and OD tolerance of -0.004mm to 0, this bearing ensures exceptional running accuracy, low noise, and minimal vibration for demanding applications.
- Optimized High-Speed Capability: The lightweight phenolic resin cage and optimized internal geometry contribute to lower centrifugal forces, allowing for a high limiting speed of 95,000 rpm.
- Sealed and Lubricated for Life: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is effectively maintenance-free within its specified temperature range of -30°C to 110°C.
S7002 CEGA/P4A Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding, and turning centers)
- Precision Grinding Spindles
- High-Frequency Motors
- Dental and Medical Handpiece Drives
- Aerospace Instrumentation
