7024 CDGC/P4A Bearing Product Overview & Core Advantages
The 7024 CDGC/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single bearing from a universally matchable (SU) pair, it excels in high-speed operations and can accommodate combined radial and axial loads. Manufactured to the stringent P4A tolerance class and featuring a moderate preload (Class C), this bearing delivers superior running accuracy, high system rigidity, and reliable performance in precision machinery and high-speed spindles.
7024 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7024 | Basic bearing designation: 120 mm bore, 180 mm OD, 28 mm width. |
| CD | Contact angle of 15°, optimized for high-speed performance and axial load capacity. |
| GC | Indicates a moderate preload (Class C) for enhanced rigidity and reduced deflection under operational loads. |
| P4A | Superior tolerance class ensuring extremely tight dimensional and running accuracy for precision applications. |
7024 CDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The 15° contact angle and factory-set moderate preload provide exceptional system stiffness and minimize axial/radial play, crucial for maintaining precision under load.
- Optimized Load Capacity: Engineered to handle significant combined radial and axial loads simultaneously, making it ideal for complex loading conditions.
- Superior High-Speed Performance: The lightweight phenolic resin cage ensures stability and low friction at the high limiting speed of 16,000 rpm, reducing centrifugal forces and heat generation.
- Universal Matchability (SU): As a universally matchable bearing, it can be paired with another identical bearing in any combination to achieve specific preload or rigidity requirements without selective mounting, simplifying inventory and assembly.
- Premium Materials: Constructed from chrome steel for rings and balls, offering high wear resistance and durability, suitable for a wide operating temperature range.
