S7004 ACE/P4BVG275 Bearing Product Overview & Core Advantages
The S7004 ACE/P4BVG275 is a precision angular contact ball bearing designed for high-performance applications. Engineered to a P4 (ABEC-7) tolerance class, it delivers exceptional running accuracy. Its key advantage lies in its ability to accommodate combined loads—simultaneously handling significant radial and axial loads in one direction. The bearing comes preloaded and lubricated from the factory, ensuring immediate high rigidity and smooth operation, making it an ideal, ready-to-install solution for high-speed, high-precision machinery.
S7004 ACE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7004 | Standard bearing series designation with a 20mm bore. |
| ACE | Specific internal design and contact angle (25°). |
| P4 | Indicates a high-precision tolerance class (equivalent to ABEC-7). |
| BVG275 | Specifies the preload level and the specific high-performance grease used for lubrication. |
S7004 ACE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity & Preload: The bearing is supplied with a preload, which eliminates internal clearance. This results in superior stiffness, minimal axial and radial runout, and precise shaft positioning, which is critical for applications like machine tool spindles.
- Superior Load Capacity: The 25° contact angle and optimized internal geometry enable it to handle high combined loads efficiently.
- High-Speed Performance: The lightweight phenolic cage ensures stability and low friction at high rotational speeds, contributing to a high limiting speed of 48,000 rpm.
- Ready-to-Use & Long-Lasting: Being factory-sealed and lubricated with specialty grease, the bearing is protected from contamination and is maintenance-free for its entire service life within the specified temperature range of -30°C to 110°C.
S7004 ACE/P4BVG275 Bearing Typical Application Areas
This bearing is ideally suited for demanding applications where high precision, high speed, and rigidity are paramount. Key industries and equipment include:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Robotic Drives and Precision Instrumentation
