SV7005 CE/P4ADGA Bearing Product Overview & Core Advantages
The SV7005 CE/P4ADGA is a metric double row angular contact ball bearing engineered for high-precision and high-rigidity applications. Its design excels at simultaneously handling combined radial and bidirectional axial loads. Manufactured to a P4A tolerance class with an extra light preload (Class A), this bearing offers exceptional running accuracy and rotational stability. The universal matchable (SU) design allows for flexible mounting arrangements in pairs, providing a compact and highly reliable solution for demanding machinery.
SV7005 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SV7005 | Basic bearing series and size designation (25mm bore, 47mm OD, 24mm width). |
| C | 15° contact angle, optimized for carrying significant axial loads. |
| E | Optimized internal design for enhanced performance. |
| /P4A | Indicates a high-precision tolerance class (P4A), superior to standard ABEC-7, ensuring minimal runout and vibration. |
| DG | Sealed on both sides. This provides superior protection against contamination. |
| A | Specifies the extra light preload (Class A), which minimizes friction and heat generation for high-speed operation. |
SV7005 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior radial and axial stiffness, enabling the bearing to withstand heavy combined loads from any direction. The 15° contact angle is ideal for applications with significant thrust loads.
High-Speed Performance: The combination of a lightweight, durable phenolic cage, extra light preload, and precision P4A grading allows for a high limiting speed of 72,500 rpm, making it suitable for high-speed spindles.
Precision & Longevity: Manufactured from chrome steel for both rings and balls, the bearing ensures high durability and wear resistance. The factory-applied grease lubrication and integrated seals offer a maintenance-free, long-service-life solution within its specified temperature range.
SV7005 CE/P4ADGA Bearing Typical Application Areas
The SV7005 CE/P4ADGA is ideally suited for high-performance applications requiring precision, speed, and rigidity, including:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Industrial Pumps & Compressors
- Robotic Drives and Actuators
- Medical and Laboratory Equipment
