S7201 CD/P4A Bearing Product Overview & Core Advantages
The S7201 CD/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Designed to accommodate combined loads (radial and axial loads in one direction), it features a 15° contact angle for optimal axial load capacity. Manufactured to P4 (ABEC-7) tolerance class, it ensures minimal runout and vibration, making it ideal for high-speed spindles and precision machinery. The bearing comes prelubricated and sealed, offering immediate installation and long-term, maintenance-free operation.
S7201 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| CD | High contact angle and optimized internal design | Enhanced axial load capacity and high-speed capability. |
| P4 | Precision tolerance class (ABEC-7) | Superior running accuracy, reduced vibration, and extended service life. |
| A | 30° contact angle variant (Note: This bearing has a 15° angle, "A" may indicate a specific internal design or preload level) | Provides high rigidity and precise shaft positioning. |
S7201 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row angular contact design, combined with a phenolic resin cage and P4 precision manufacturing, delivers exceptional dimensional stability and stiffness, minimizing deflection under load.
- Superior Load Capacity: Engineered to handle significant combined radial and axial loads simultaneously. The 15° contact angle is optimized for applications where axial loads are prominent.
- High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, allowing for a high limiting speed of 53,000 rpm. The optimized internal geometry minimizes friction and heat generation.
- Ready-to-Use & Long-Lasting: As a sealed and prelubricated bearing, it is protected from contamination and is lubricated for life within its specified temperature range (-30°C to 110°C), ensuring reliable, maintenance-free operation.
S7201 CD/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles
- High-Speed Motors and Spindles
- Precision Grinding Equipment
- Robotic Arms and Rotary Tables
- Medical and Dental Equipment
