S7013 ACE/P4BVG275 Bearing Product Overview & Core Advantages
The S7013 ACE/P4BVG275 is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, this bearing is preloaded and capable of supporting combined loads, handling both radial forces and substantial axial loads in one direction. Its compact design, featuring a phenolic cage and factory-applied lubrication, makes it an ideal solution for high-speed spindles and other precision machinery where reliability and long service life are critical.
S7013 ACE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| S7013 | Basic Series & Size | Denotes a 65 mm bore, 100 mm OD, 18 mm width bearing from the 7013 series. |
| ACE | Contact Angle & Design | Signifies a 25° contact angle and a specific internal design optimized for high stiffness and speed. |
| P4 | Tolerance Class | Corresponds to ABEC-7, indicating ultra-high precision in dimensions and running accuracy. |
| BVG275 | Cage & Lubrication | Indicates a phenolic resin cage (for high speeds) and a specific, high-performance grease suitable for the stated temperature range. |
S7013 ACE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row angular contact design, combined with a 25° contact angle and P4 precision, provides exceptional stiffness and running accuracy, minimizing deflection under load.
- Superior Load Capacity: Engineered to support significant combined (radial and axial) loads. With a dynamic load rating of 4388 lbf and a static load rating of 3285 lbf, it offers robust performance in demanding conditions.
- Optimized High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, enabling a high limiting speed of 17,000 rpm. The pre-applied, high-quality grease ensures stable lubrication at these elevated speeds.
- Sealed and Pre-Lubricated: As a sealed bearing, it is protected from contamination. Being factory-lubricated makes it ready for immediate installation, reducing maintenance needs.
S7013 ACE/P4BVG275 Bearing Typical Application Areas
