S7004 CE/P4A Bearing Product Overview & Core Advantages
The S7004 CE/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. As a single-row bearing, it excels at handling combined loads—simultaneously supporting high radial loads and substantial axial loads in one direction. Manufactured to P4 (ABEC-7) tolerance class, it ensures superior running accuracy and rotational precision. The bearing comes preloaded and pre-lubricated, making it ready for immediate installation in high-performance systems requiring high rigidity and high-speed operation.
S7004 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7004 | Standard designation for a 20mm bore, 42mm OD angular contact ball bearing. |
| CE | Indicates a 15° contact angle and a specific internal design optimized for high-speed performance and rigidity. |
| P4A | Denotes a P4 (ABEC-7) tolerance class with enhanced dimensional and running accuracy specifications. |
S7004 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 15° contact angle and P4 precision provides excellent rotational stability and minimizes deflection under load, which is critical for high-precision spindles.
- Superior Load Capacity: Engineered to handle significant combined radial and axial loads, making it ideal for applications with complex loading conditions.
- Optimized High-Speed Performance: The phenolic resin cage (Phenolic) offers low weight and excellent performance at high rotational speeds, contributing to the bearing's high limiting speed.
- Ready-to-Use & Reliable: The bearing is supplied sealed and pre-lubricated, protecting against contamination and providing long-term, maintenance-free operation within its specified temperature range.
