7024 CDGD/P4A Bearing Product Overview & Core Advantages
The 7024 CDGD/P4A is a single row angular contact ball bearing engineered for applications demanding high precision and exceptional rigidity. Designed to accommodate primarily axial loads in one direction and combined loads, its P4A tolerance class and Heavy preload (Class D) ensure superior rotational accuracy and minimal deflection under demanding conditions. This bearing is universally matchable (SU), allowing for precise axial clearance control when mounted with a second, suitably selected bearing, making it ideal for high-performance spindles and precision machinery.
7024 CDGD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7024 | Basic bearing designation indicating a 120 mm bore, 180 mm OD, and 28 mm width. |
| C | Specifies a 15° contact angle, optimized for high axial load capacity. |
| DG | Indicates the bearing is supplied as a universally matchable (SU) pair (2 bearings). |
| D | Signifies a Heavy preload (Class D) for maximum system rigidity. |
| P4A | Denotes an ultra-precision tolerance class with enhanced running accuracy. |
7024 CDGD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The combination of a 15° contact angle and Heavy preload (Class D) provides outstanding system stiffness, minimizing axial and radial displacement under load. The P4A tolerance class ensures exceptional dimensional and running accuracy.
- Superior Load Capacity: Engineered to handle high axial loads in one direction and combined (radial and axial) loads efficiently, thanks to its optimized raceway geometry and chrome steel construction.
- Optimized High-Speed Performance: The lightweight, high-strength phenolic cage reduces centrifugal forces, contributing to a high limiting speed of 16,000 rpm. The standard lubrication is suitable for this operational range.
- Universal Matching Capability (SU): This feature allows for precise axial clearance or preload adjustment when mounted with a second, universally matched bearing, simplifying assembly and optimizing performance in duplex arrangements.
7024 CDGD/P4A Bearing Typical Application Areas
The 7024 CDGD/P4A is ideally suited for high-precision, high-rigidity applications, including:
- Machine Tool Spindles (e.g., CNC machining centers, grinding spindles)
- High-Frequency Motors
- Precision Robotics and Automation Equipment
- Aerospace & Defense Positioning Systems
