S7004 CE/P4ADGA Bearing Product Overview & Core Advantages
The S7004 CE/P4ADGA is a high-precision, double row angular contact ball bearing engineered for applications demanding exceptional accuracy and rigidity. Its design enables it to simultaneously support substantial combined loads (radial and bidirectional axial loads) with high running accuracy. Featuring an Extra Light (A) preload and a P4A tolerance class, this bearing is optimized for high-speed operation and offers superior rotational stability, making it an ideal choice for high-reliability, precision machinery.
S7004 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates a universally matchable bearing designed for flexible mounting arrangements in pairs. |
| P4A | Denotes an ultra-high precision tolerance class, exceeding ABEC 7 standards, for minimal runout and vibration. |
| DGA | Signifies a sealed bearing, pre-lubricated with grease, offering protection from contamination and enabling maintenance-free operation. |
S7004 CE/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and 15° contact angle provide high rigidity and enable the bearing to handle significant combined radial and axial loads from both directions, ensuring stable shaft support.
- Superior High-Speed Performance: The phenolic cage is lightweight and robust, contributing to lower friction and higher limiting speeds. Combined with the optimized grease lubrication, it ensures reliable performance at high RPMs.
- Precision & Stability: Manufactured to P4A tolerance and with an Extra Light preload, this bearing guarantees high running accuracy, minimal deflection, and reduced vibration for precise applications.
- Maintenance-Free Operation: The integrated seals effectively retain lubricant and exclude contaminants, while the pre-applied grease offers a long service life within the specified temperature range of -30°C to 110°C.
S7004 CE/P4ADGA Bearing Typical Application Areas
This bearing is ideally suited for high-performance machinery requiring precision and speed, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Advanced Robotics and Automation Equipment
