S7009 ACE/P4BVG275 Bearing Product Overview & Core Advantages
The S7009 ACE/P4BVG275 is a precision angular contact ball bearing designed for applications requiring exceptional rotational accuracy and rigidity. As a single-row bearing with a 25° contact angle and P4 (ABEC-7) tolerance class, it excels at supporting combined radial and axial loads simultaneously. Its sealed design and factory-applied lubrication ensure long-term, maintenance-free operation, making it an ideal choice for high-speed spindles and other demanding precision machinery.
S7009 ACE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| ACE | Specific internal design and contact angle (25°) | Optimized for high axial load capacity and rigidity |
| P4 | Tolerance class equivalent to ABEC-7 | Ensures ultra-precise running accuracy and minimal vibration |
| BVG275 | Sealed bearing with specific high-performance grease | Provides contamination protection and extended lubrication life |
S7009 ACE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 25° contact angle and precision-ground raceways enable superior resistance to combined loads, making it suitable for applications with significant axial and radial forces.
- Precision Performance: Manufactured to P4 tolerance class with a phenolic resin cage, this bearing delivers exceptional running accuracy and stability, essential for high-speed applications.
- Optimized High-Speed Operation: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 24,000 rpm, reducing centrifugal forces and operational temperatures.
- Maintenance-Free Design: Integrated seals and pre-lubrication with high-performance grease provide reliable, long-term operation without requiring re-lubrication, even within its specified temperature range of -30°C to 110°C.
S7009 ACE/P4BVG275 Bearing Typical Application Areas
- Machine Tool Spindles: High-precision machining centers, grinding spindles, and CNC milling machines
- High-Speed Motors & Drives: Servo motors, spindle motors, and high-frequency electric motors
- Precision Instrumentation: Medical equipment, optical instruments, and measuring devices
