S7007 ACE/P4BVG275 Bearing Product Overview & Core Advantages
The S7007 ACE/P4BVG275 is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, this bearing excels in high-speed scenarios, with a limiting speed of 31,000 rpm. Its 25° contact angle is optimized to support significant combined loads, managing both radial and axial forces simultaneously. The integrated phenolic cage and factory-applied lubrication ensure reliable, long-term performance in high-rigidity spindle and precision machinery arrangements.
S7007 ACE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7007 | Series designation for a 35mm bore, 62mm OD, 14mm width angular contact bearing. |
| ACE | Indicates a 25° contact angle and a specific internal design for optimized load distribution. |
| P4 | Denotes the precision tolerance class (equivalent to ABEC-7), ensuring minimal runout and vibration. |
| BVG275 | Specifies the cage material (phenolic/resin) and the type of preload and lubrication used. |
S7007 ACE/P4BVG275 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single-row design with a 25° contact angle provides excellent resistance to combined loads, with a dynamic load rating of 2498 lbf and a static load rating of 1418 lbf. This makes it ideal for applications requiring high stiffness and stability.
High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the optimized internal geometry and pre-applied lubrication contribute to a high limiting speed of 31,000 rpm, making it a true high-speed bearing.
Precision & Reliability: Manufactured to P4 tolerance with chrome steel rings and balls, this bearing guarantees minimal dimensional variation and smooth operation, which is critical for precision machinery.
Sealed & Lubricated for Life: As a sealed bearing with factory lubrication, it is protected from contamination and is ready for installation, offering a maintenance-free solution within its specified temperature range of -30°C to 110°C.
S7007 ACE/P4BVG275 Bearing Typical Application Areas
