S7200 CD/P4A Bearing Product Overview & Core Advantages
The S7200 CD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered with P4 (ABEC-7) tolerance class, it delivers superior running precision for high-performance machinery. Its key advantage lies in its ability to accommodate combined loads—simultaneously handling radial and axial forces—thanks to its specific 15° contact angle. The bearing comes preloaded and lubricated from the factory, ensuring immediate operational readiness, high stiffness, and reliable performance in high-speed applications up to 60,000 rpm.
S7200 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| CD | 15° contact angle and specific internal design | Optimized for high rigidity and combined load capacity. |
| P4A | P4 (ABEC-7) tolerance class | Guarantees extremely high running accuracy and dimensional precision. |
S7200 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Preload: The angular contact design, combined with a factory-applied preload, eliminates internal clearance. This results in significantly increased system stiffness, critical for minimizing deflection under load in precision applications.
- Superior Load Capacity: The 15° contact angle enables the bearing to efficiently support substantial combined radial and axial loads, making it ideal for applications with complex loading conditions.
- High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the optimized internal geometry and effective lubrication contribute to a high limiting speed of 60,000 rpm.
- Sealed & Lubricated for Life: As a sealed bearing, it is protected from contamination. Pre-greased with high-quality lubricant, it operates reliably within a temperature range of -30°C to 110°C, offering a maintenance-free service life.
S7200 CD/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance equipment where accuracy and speed are paramount. Key industries and applications include:
- Machine Tool Spindles: High-speed machining centers, grinding spindles.
- Precision Drives: Servo motors, high-frequency spindles.
- Aerospace & Defense: Gyroscopes, navigation systems, auxiliary power units.
- Medical Equipment: Dental handpieces, laboratory centrifuges.
