7226 CD/P4A Bearing Product Overview & Core Advantages
The 7226 CD/P4A is a single-row angular contact ball bearing engineered for applications demanding high precision and superior running accuracy. Operating under the P4 (ABEC-7) tolerance class, it is designed to handle significant combined loads—primarily thrust loads in one direction alongside radial loads. Its optimized internal geometry, featuring a 15° contact angle, ensures high rigidity and exceptional performance in high-speed scenarios, making it an ideal choice for precision spindles and other critical machinery components.
7226 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| CD | Optimized internal design for high rigidity and load capacity | Enhances the bearing's ability to withstand heavy combined loads and maintain stability. |
| P4A | High-Precision Tolerance Class (equivalent to ABEC-7) | Guarantees tight dimensional and running accuracy, essential for high-speed and low-vibration applications. |
7226 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single-row design with a 15° contact angle and optimized internal geometry (CD suffix) provides high resistance to deformation under load, enabling reliable operation under substantial radial and axial loads.
- Superior High-Speed Performance: The lightweight and robust phenolic resin cage ensures excellent dimensional stability and low friction at high rotational speeds, contributing to the high limiting speed of 9,500 rpm.
- Precision Engineering: Manufactured to P4 tolerance class, this bearing offers minimal runout and vibration, which is critical for applications requiring smooth and precise rotation.
- Premium Material Construction: Manufactured from high-grade chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long operational life.
- Preload Availability: The bearing is supplied with a preload, which increases system stiffness, improves rotational accuracy, and reduces noise and vibration.
7226 CD/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- High-Speed Pumps and Compressors
- Aerospace and Defense Instrumentation
