7024 CB/P4A Bearing Product Overview & Core Advantages
The 7024 CB/P4A is a single-row angular contact ball bearing engineered for applications demanding exceptional precision and rigidity. Positioned in the P4 (ABEC-7) tolerance class, it delivers superior running accuracy for high-performance machinery. Its key advantage lies in its ability to accommodate significant combined loads—handling both radial and substantial axial loads in one direction efficiently. The bearing comes preloaded, ensuring zero clearance for enhanced stiffness and precise shaft positioning, making it an ideal choice for high-speed and high-precision applications.
7024 CB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CB | Specific internal clearance and preload designation | Provides controlled preload for optimal rigidity and rotational accuracy. |
| P4A | Tolerance class equivalent to ABEC-7 (P4) with specific dimensional and running accuracy requirements. | Ensures ultra-precise performance, low noise, and low vibration for demanding applications. |
7024 CB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row design with a 15° contact angle and factory-applied preload eliminates internal clearance, resulting in exceptional system stiffness and precise shaft guidance, crucial for minimizing deflection under load.
- Superior Load Capacity: Engineered to handle high radial dynamic load ratings (8482 lbf) and static load ratings (8775 lbf), along with substantial one-direction axial loads, making it suitable for combined load conditions.
- Optimized High-Speed Performance: The lightweight and robust phenolic resin cage ensures stable operation and guides the balls effectively, contributing to the high limiting speed of 14,000 rpm. The open design facilitates efficient lubrication management.
- Premium Material Construction: Manufactured from chrome steel for both rings and balls, the bearing offers high hardness, wear resistance, and a long operational life. It is supplied lubricated for immediate installation and operation.
