7024 CD/P4A Bearing Product Overview & Core Advantages
The 7024 CD/P4A is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Positioned in the P4 (ABEC-7) tolerance class, this bearing is designed to handle significant combined loads, including high radial loads and unidirectional axial loads, thanks to its 15° contact angle. Its phenolic resin cage and optimized internal geometry contribute to superior high-speed performance, making it an ideal component for demanding, high-accuracy machinery where reliability is paramount.
7024 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7024 | Standard bearing series designation, indicating bore diameter: 120 mm, outside diameter: 180 mm, and width: 28 mm. |
| CD | Indicates a specific internal design with optimized contact angle and internal clearance for high rigidity and preload capability. |
| P4A | Specifies the tolerance class P4 (ABEC-7), denoting very high dimensional and running accuracy. The 'A' suffix may indicate specific accuracy enhancements or grouping for matched arrangements. |
7024 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4 tolerance class with a 15° contact angle, this bearing provides stable and precise shaft positioning, essential for applications with minimal deflection requirements.
- Superior Load Capacity: The optimized internal geometry and use of chrome steel for rings and balls enable high radial dynamic load rating (25,650 lbf) and static load rating (27,450 lbf), effectively handling combined loads.
- Optimized High-Speed Performance: The lightweight phenolic resin cage ensures lower centrifugal forces and excellent dimensional stability at high speeds, supporting a limiting speed of 11,000 rpm.
- Preload and Matched Set Capability: The CD designation signifies the bearing is suitable for preloading, which increases system stiffness. It can be supplied as a single unit or selected for matched arrangements to achieve specific preload levels in duplex sets.
7024 CD/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for high-performance machinery, including:
- Machine Tool Spindles (e.g., milling, grinding, and lathe spindles)
- High-Speed Precision Spindles for PCB drilling and routing
- Industrial Pumps and Compressors
- Robotic Arm Joints and Precision Gearboxes
- Medical and Laboratory Equipment requiring high rotational accuracy
