71824 CDGC/P4 Bearing Product Overview & Core Advantages
The 71824 CDGC/P4 is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Operating under the stringent P4 tolerance class, this bearing is engineered to handle combined loads, efficiently supporting both radial forces and substantial axial loads in one direction. Its moderate preload (Class C) ensures optimal stiffness and minimizes deflection under operational stresses. Manufactured from high-grade chrome steel and featuring a lightweight phenolic cage, it is ideally suited for high-speed applications and high-reliability systems where precision and performance are paramount.
71824 CDGC/P4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71824 | Basic bearing designation, defining the core dimensions (120mm bore, 150mm OD, 16mm width). |
| CD | Specifies a 15° contact angle, optimized for handling high axial loads. |
| GC | Indicates the moderate preload (Class C) for enhanced system rigidity. |
| P4 | Denotes the high-precision tolerance class, ensuring minimal running tolerances for superior accuracy. |
71824 CDGC/P4 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design and Class C preload work in tandem to provide exceptional stiffness, effectively resisting operational deflection. This enables the bearing to support significant combined radial and axial loads.
- Optimized High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the 15° contact angle and precision manufacturing contribute to a high limiting speed of 16,250 rpm, making it a true high-speed bearing.
- Precision Engineering: As a P4 tolerance class bearing, it features extremely tight dimensional and running accuracy, which is critical for applications requiring minimal vibration and runout.
- Universal Matching Capability (SU): This bearing is Universal Matchable, allowing two bearings to be mounted in a back-to-back (DB), face-to-face (DF), or tandem (DT) arrangement without selective assembly, simplifying installation and improving system performance.
71824 CDGC/P4 Bearing Typical Application Areas
The 71824 CDGC/P4 is deployed in high-performance machinery where precision, speed, and rigidity are non-negotiable. Key sectors include:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers.
- Precision Gearboxes: Especially in robotics and high-end automotive transmissions.
- High-Frequency Motors and Spindles: Used in CNC machining and PCB drilling equipment.
- Aerospace Actuation Systems: Where reliability and accuracy under load are critical.
