S7024 ACD/P4A Bearing Product Overview & Core Advantages
The S7024 ACD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing with a 25° contact angle and P4 (ABEC-7) tolerance class, it is engineered to handle combined loads, accommodating significant axial loads in one direction alongside radial loads. Its preload availability ensures minimal axial and radial play, resulting in high system stiffness, precise shaft positioning, and smooth operation at high speeds, making it ideal for high-performance, high-reliability machinery.
S7024 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7024 | Basic bearing series and size designation (120mm bore, 180mm OD). |
| ACD | Angular Contact design with a 25° contact angle and optimized internal geometry. |
| P4A | Indicates a P4 (ABEC-7) tolerance class for superior running accuracy and a specific preload level for high rigidity. |
S7024 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 25° contact angle and preload provides high axial and radial stiffness, critical for applications requiring precise shaft guidance and minimal deflection under load.
- Superior Load Capacity: Engineered to support high combined radial and axial loads, with a dynamic load rating of 24,975 lbf and a static load rating of 26,100 lbf.
- Optimized High-Speed Performance: The phenolic resin cage offers low weight and excellent sliding properties, contributing to a high limiting speed of 6,700 rpm. The standard lubrication ensures stable operation across this range.
- Durability and Reliability: Manufactured from chrome steel for both rings and balls, this bearing ensures long service life and consistent performance within a temperature range of -30°C to 110°C.
- Sealed and Lubricated for Life: As a sealed and pre-lubricated unit, it is protected from contamination and is ready for installation, reducing maintenance requirements.
