S7014 ACE/P4BVG275 Bearing Product Overview & Core Advantages
The S7014 ACE/P4BVG275 is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. Engineered to a P4 (ABEC-7) tolerance class, this bearing excels at simultaneously handling combined radial and axial loads. Its compact design, featuring a 20mm width, makes it an ideal solution for high-speed spindles and precision machinery where space is at a premium and high rigidity is paramount.
S7014 ACE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| ACE | Specific internal design and contact angle (25°) | Optimized for high axial load capacity and precise operation. |
| P4 | Tolerance class equivalent to ABEC-7 | Ensures ultra-precise running accuracy, low vibration, and low noise. |
| BVG | Sealed and pre-lubricated | Provides contamination protection and long-term, maintenance-free operation. |
| 275 | Internal designation for preload and fit | Delivers consistent, high-stiffness performance in the assembled application. |
S7014 ACE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to a P4 tolerance class with a 25° contact angle, this bearing provides superior rotational accuracy and stiffness, minimizing deflection under load.
- Superior Load Capacity: The angular contact design is engineered to support significant combined loads, with a dynamic load rating of 5062 lbf and a static load rating of 3892 lbf.
