S7004 CE/P4BVG275 Bearing Product Overview & Core Advantages
The S7004 CE/P4BVG275 is a precision angular contact ball bearing designed for high-performance applications requiring exceptional accuracy and reliability. Engineered to simultaneously handle combined radial and axial loads, this bearing features a 15° contact angle and is supplied with a preload for enhanced system rigidity. Manufactured to P4 (ABEC-7) tolerance class, it ensures minimal runout and superior rotational accuracy. Its compact design, sealed construction, and pre-lubrication make it an ideal high-speed bearing solution for demanding machinery.
S7004 CE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7004 | Basic bearing series and size designation (20mm bore, 42mm OD, 12mm width). |
| CE | Indicates a specific internal design and contact angle (15°) optimized for high-speed operation and rigidity. |
| P4 | Denotes the tolerance class (ABEC-7), signifying ultra-precision manufacturing for minimal vibration and high running accuracy. |
| BVG275 | Specifies the cage material (Phenolic) and likely a specific lubrication or sealing designation, contributing to low friction and high-speed capability. |
S7004 CE/P4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity and Preload: The single, matched arrangement with applied preload eliminates internal clearance, providing superior stiffness and precise shaft positioning, critical for minimizing deflection under load.
- Superior Load Capacity: The angular contact design with a 15° contact angle enables the bearing to efficiently support combined loads (radial and axial loads acting simultaneously).
- Optimized High-Speed Performance: The lightweight phenolic cage ensures stability and low centrifugal forces at high rotational speeds, supporting a limiting speed of 54,000 rpm. The bearing is pre-lubricated for immediate operation.
- Sealed and Lubricated for Longevity: The sealed construction protects against contamination and retains lubricant, offering a maintenance-free service life within the specified operating range.
- Precision Materials: Components made from chrome steel provide high hardness, wear resistance, and durability for extended service life in precision applications.
