S7005 CEGA/HCP4A Bearing Product Overview & Core Advantages
The S7005 CEGA/HCP4A is a high-precision, single-row angular contact ball bearing engineered for exceptional performance in demanding applications. Its core advantages stem from its P4A super-precision tolerance class and universal matchable (SU) design, allowing for precise preload control when mounted in pairs. The combination of a ceramic ball material and a phenolic cage enables superior high-speed capabilities and reduced rotational mass. This bearing is designed to handle combined loads with high reliability and is pre-lubricated for immediate, maintenance-free operation.

| Code Segment | Technical Meaning |
|---|---|
| S7005 | Denotes the basic bearing series and size (25mm bore, 47mm OD, 12mm width). |
| CEGA | Indicates a sealed bearing, protecting against contamination. |
| HCP4A | Specifies the P4A super-precision tolerance and the use of hybrid ceramic balls for enhanced speed and performance. |
S7005 CEGA/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Design: The use of ceramic balls significantly reduces weight and inertia, lowers operating temperature, and provides excellent performance at high rotational speeds (up to 83,000 rpm).
- Precision & Rigidity: Manufactured to P4A tolerance class with a 15° contact angle, this bearing delivers exceptional running accuracy, high system rigidity, and precise shaft positioning.
- Optimized for High Speed: The lightweight phenolic cage is ideal for high-speed operation, ensuring stability and reduced friction.
- Sealed & Lubricated for Life: The integral seals retain the factory-applied grease lubrication, making the bearing ready-to-install and suitable for applications requiring maintenance-free operation within a temperature range of -30°C to 110°C.
