S7024 CDGB/P4A Bearing Product Overview & Core Advantages
The S7024 CDGB/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. As a single bearing that is Universal Matchable (SU), it can be paired to form a precisely preloaded set, offering superior performance in compact installations. Its P4A tolerance class ensures extremely tight dimensional control for high-speed, high-accuracy spindles. The bearing is pre-lubricated with grease and features integrated seals, making it a ready-to-install solution for high-rigidity and high-speed applications.
S7024 CDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7024 | Basic bearing designation, indicating a 120mm bore, 180mm OD, and 28mm width. |
| C | Specifies a 15° contact angle, optimized for high-speed operation and handling combined loads. |
| DGB | Indicates a Universal Matchable (SU) bearing designed for a Light preload (Class B) when paired in a back-to-back (DB) arrangement. |
| P4A | Denotes an ultra-precision tolerance class with extremely tight limits on bore, outside diameter, and width tolerances for superior running accuracy. |
S7024 CDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design and phenolic cage enable the bearing to support significant combined radial and axial loads simultaneously. The universal matching feature allows for the creation of a rigid, preloaded bearing set that minimizes deflection under load.
- Superior High-Speed Performance: The 15° contact angle and lightweight phenolic resin cage are optimized for low friction and high rotational stability, contributing to a high limiting speed of 11,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for the accuracy of machine tool spindles and other precision equipment.
- Sealed and Pre-Lubricated: The integrated seals protect against contamination, and the factory-applied grease lubrication ensures immediate operation and long service life within a specified temperature range of -30°C to 110°C.
S7024 CDGB/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles (e.g., CNC milling machines, grinding spindles)
- High-Speed Machining Centers
- Precision Grinding Equipment
- Industrial Pumps and Compressors
- High-Frequency Motors
