7024 CD/P4ADBB Bearing Product Overview & Core Advantages
The 7024 CD/P4ADBB is a precision duplex angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high rigidity. This matched back-to-back arrangement (DB) enables the bearing to simultaneously handle combined radial and axial loads from both directions. Manufactured to P4A tolerance class and featuring a light preload (Class B), it delivers superior running accuracy and stability, making it ideal for high-speed, high-precision machinery where uncompromising performance is critical.
7024 CD/P4ADBB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Duplex bearing with a 15° contact angle and specific internal radial clearance/preload. |
| P4A | Indicates a high-precision tolerance class with enhanced dimensional and running accuracy requirements. |
| DB | Signifies the Back-to-Back matched arrangement, providing high moment stiffness and stability. |
7024 CD/P4ADBB Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) configuration creates a wide effective spread, significantly increasing system rigidity and resistance to moment loads, ensuring precise shaft positioning.
- Superior Load Capacity: Engineered with a 15° contact angle, this bearing is optimized to carry substantial combined radial and axial loads simultaneously, making it suitable for demanding applications.
- High-Speed Capability: The lightweight and robust phenolic resin cage ensures excellent dimensional stability and low friction at high rotational speeds, contributing to a limiting speed of 16,000 rpm.
- Precision Performance: Manufactured to P4A tolerance standards with a light preload, it guarantees minimal runout, reduced vibration, and smooth, accurate operation.
7024 CD/P4ADBB Bearing Typical Application Areas
This bearing is predominantly used in high-performance machinery requiring high precision and speed, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Aerospace and Defense Positioning Systems
