S7007 CE/P4A Bearing Product Overview & Core Advantages
The S7007 CE/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to P4 (ABEC-7) tolerance class, this bearing excels in handling combined loads, simultaneously supporting significant radial and axial forces. Its compact design, featuring a 35 mm bore and 14 mm width, makes it ideal for space-constrained, high-performance assemblies. The combination of a phenolic cage and preload ensures smooth operation at high speeds with minimal vibration, making it a superior choice for mission-critical applications.
S7007 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| S7007 | Bearing series and size designation | Indicates a 35mm bore, 62mm OD, 14mm width bearing from a specific high-performance series. |
| CE | High-precision contact angle optimization | Denotes a 15° contact angle optimized for high-speed operation and axial load capacity. |
| P4A | Tolerance class and preload specification | Signifies P4 (ABEC-7) precision and a specific axial preload for enhanced rigidity and running accuracy. |
S7007 CE/P4A Bearing Structural Features & Performance Benefits
High Rigidity and Running Accuracy: The angular contact design, combined with the specified axial preload (P4A), eliminates internal clearance, resulting in exceptional shaft positioning accuracy and resistance to operational deflection under load.
Superior Load Capacity: The 15° contact angle and robust construction enable the bearing to handle significant combined radial and axial loads simultaneously, a critical requirement for precision spindles.
High-Speed Performance: The lightweight phenolic resin cage ensures excellent dimensional stability and low friction at high rotational speeds, contributing to a limiting speed of 34,000 rpm. The optimized internal geometry minimizes heat generation.
Precision Materials: Manufactured from chrome steel for both rings and balls, the bearing offers high hardness, wear resistance, and long-term dimensional stability.
