7009 ACD/P4A Bearing Product Overview & Core Advantages
The 7009 ACD/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single bearing with preload availability, it is engineered to handle significant combined loads—simultaneously supporting radial and axial loads. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it ideal for high-speed, high-reliability machinery where precise shaft positioning is critical.
7009 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Designates a 25° contact angle and optimized internal geometry for high axial load capacity and rigidity. |
| P4A | Indicates a P4 tolerance class (equivalent to ABEC-7) with specific running accuracy requirements for the shaft and housing fits. |
7009 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 25° contact angle and robust internal construction provide high resistance to deformation under combined loads, ensuring stable operation.
- Precision & High-Speed Performance: Manufactured to P4 tolerance and featuring a lightweight phenolic cage, this bearing achieves a high limiting speed of 26,000 rpm with minimal vibration.
- Optimized Internal Geometry: With a bore diameter of 45 mm and 17 precision balls of 9.525 mm diameter, the load is distributed evenly for smooth, quiet running.
- Preload Availability: The option for preload allows for elimination of axial play, enhancing system stiffness and rotational accuracy in the final application.
7009 ACD/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for:
- Machine Tool Spindles
- High-Speed Machining Centers
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Robotic Arm Joints and Precision Positioning Systems
