S7206 CD/P4A Bearing Product Overview & Core Advantages
The S7206 CD/P4A is a metric single-row angular contact ball bearing engineered for applications demanding high precision and superior rotational accuracy. Positioned in the P4 (ABEC-7) tolerance class, it is designed to handle significant combined loads—primarily thrust loads in one direction with radial loads. Its 15° contact angle and preload availability contribute to high system rigidity and precise shaft positioning, making it an ideal choice for high-speed, high-reliability machinery where minimal runout and vibration are critical.
S7206 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| C | Designates a 15° contact angle, optimized for high-speed applications requiring thrust capacity. |
| D | Indicates a high-precision phenolic resin cage, contributing to low friction, high-speed capability, and reduced weight. |
| P4A | Specifies the P4 (ABEC-7) tolerance class with specific running accuracy requirements, ensuring exceptional dimensional and running precision. |
S7206 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Axial Load Capacity: The single-row design with a 15° contact angle provides excellent resistance to axial loads in one direction while supporting radial loads, resulting in high system stiffness and precise axial positioning.
- High-Speed Performance: The lightweight phenolic cage (suffix D) reduces centrifugal forces and ensures stable operation at the high limiting speed of 24,000 rpm. The optimized internal geometry minimizes friction and heat generation.
- Precision & Accuracy: Manufactured to P4 (ABEC-7) tolerance standards with tight dimensional controls on the 30 mm bore and 62 mm outside diameter, this bearing guarantees minimal runout and vibration for demanding applications.
- Sealed & Lubricated for Life: As a sealed and pre-lubricated unit, it is protected from contamination and is ready for immediate installation, offering long-term, maintenance-free operation within its specified temperature range.
S7206 CD/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for:
- Machine Tool Spindles (high-speed milling, grinding)
- Precision Gearboxes and High-Frequency Motors
- Industrial Pumps and Compressors
- Robotic Arms and Automation Equipment
- Medical and Dental Equipment spindles
