S7012 ACE/P4BVG275 Bearing Product Overview & Core Advantages
The S7012 ACE/P4BVG275 is a high-precision angular contact ball bearing designed for applications demanding exceptional rigidity and rotational accuracy. As a single-row bearing with a 25° contact angle, it excels at handling combined radial and axial loads simultaneously. Manufactured to P4 (ABEC-7) tolerance class, it delivers superior running accuracy, making it ideal for high-speed spindles and other precision machinery where reliability and performance are critical.
S7012 ACE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7012 | Basic bearing series and size designation. |
| ACE | Specific internal design, including optimized contact angle and internal geometry for high performance. |
| P4 | Indicates a high-precision tolerance class (equivalent to ABEC-7), ensuring minimal runout and vibration. |
| BVG275 | Specifies the preload level and likely a specific high-performance grease lubrication suitable for the defined temperature range. |
S7012 ACE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 25° contact angle and robust construction enable the bearing to support significant combined loads, providing stable and rigid support for spindles.
- Superior High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 18,000 rpm. This makes it an excellent high-speed bearing.
- Precision Engineering: Manufactured to P4 tolerance with a bore diameter tolerance of -0.007mm to 0, it guarantees exceptional running accuracy and low noise operation.
- Optimized for Longevity: The bearing comes pre-lubricated and is sealed, protecting against contamination and ensuring consistent performance within its specified temperature range of -30°C to 110°C.
