S7024 CD/P4A Bearing Product Overview & Core Advantages
The S7024 CD/P4A is a precision double row angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. Engineered to simultaneously handle combined radial and bidirectional axial loads, this bearing features a compact design ideal for high-precision, high-reliability machinery. Its P4 (ABEC-7) tolerance class and available preload ensure superior running accuracy and minimal vibration, making it a top-tier solution for high-performance systems.
S7024 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7024 | Basic bearing series and size designation (120mm bore, 180mm OD). |
| CD | Indicates a specific contact angle (15°) and internal design optimized for high rigidity and precise load distribution. |
| P4A | Denotes a high-precision tolerance class (P4/ABEC-7) with enhanced dimensional and running accuracy specifications. |
S7024 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and optimized 15° contact angle provide significantly increased rigidity and the ability to handle substantial combined loads from multiple directions.
- Precision & High-Speed Performance: The phenolic resin cage offers low weight and excellent high-speed stability, contributing to the bearing's limiting speed of 7,000 rpm. The P4 tolerance ensures smooth, precise operation.
- Durability & Reliability: Manufactured from high-grade chrome steel for both rings and balls, the bearing delivers long service life and consistent performance. It comes pre-lubricated and sealed for protection against contamination.
- Optimized Internal Geometry: With a ball diameter of 19.05 mm and a quantity of 22 balls, the design maximizes load distribution and rotational smoothness.
