7024 CDGA/P4A Bearing Product Overview & Core Advantages
The 7024 CDGA/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and performance. Engineered with an Extra Light (Class A) preload and manufactured to P4A tolerance class, this bearing delivers superior running accuracy, high rigidity, and reliable operation. Its 15° contact angle is optimized to handle combined loads, efficiently supporting significant radial loads alongside axial loads in one direction. The phenolic resin cage and universal matching (SU) designation make it ideal for high-speed spindle arrangements and other high-precision machinery.
7024 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CDGA | Indicates a universally matchable bearing with a specific internal design (contact angle and preload) that allows it to be mounted in pairs (back-to-back, face-to-face, or tandem) to achieve the desired rigidity and load capacity. |
| P4A | Denotes an ultra-precision tolerance class exceeding ABEC 7 standards, ensuring minimal runout and vibration for superior performance in high-speed applications. |
7024 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The angular contact design combined with the Class A preload eliminates internal clearance, providing immediate system stiffness and precise rotational accuracy, which is critical for machine tool spindles.
- Superior Load Capacity: With a dynamic load rating of 25,650 lbf and a static load rating of 27,450 lbf, this bearing is engineered to handle demanding combined radial and axial loads.
- Optimized High-Speed Performance: The lightweight phenolic resin cage ensures low inertia and excellent performance at high rotational speeds, with a limiting speed of 16,000 rpm. The open design allows for efficient lubrication management.
- Universal Matchability (SU): This feature allows for simplified mounting of bearing pairs without selective matching, reducing assembly time and ensuring consistent, predictable performance in preloaded sets.
7024 CDGA/P4A Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Grinding Equipment
- High-Frequency Motors
- Medical and Dental Equipment Spindles
- Aerospace Positioning Systems
