7226 ACD/P4A Bearing Product Overview & Core Advantages
The 7226 ACD/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. This P4 (ABEC-7) tolerance class bearing is designed to handle significant combined loads, accommodating high radial loads and thrust loads in one direction simultaneously. Its optimized internal geometry, including a 25° contact angle, provides superior axial rigidity and operational stability. Pre-lubricated and featuring a lightweight phenolic cage, it is an ideal solution for high-speed spindles and other demanding machinery.
7226 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7226 | Basic bearing series and size designation (130mm bore, 230mm OD). |
| AC | Angular Contact design with a 25° contact angle. |
| D | Signifies a high-load capacity internal design. |
| P4A | Indicates a P4 (ABEC-7) tolerance class with specific running accuracy requirements. |
7226 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The optimized 25° contact angle and robust internal construction enable the bearing to support high combined radial and axial loads with minimal deflection, ensuring system stability.
- High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground chrome steel balls and raceways contribute to smooth operation at the specified limiting speed of 8,500 rpm.
- Precision Operation: Manufactured to P4 (ABEC-7) tolerance class, this bearing guarantees extremely tight dimensional and running accuracy, which is critical for applications requiring minimal runout and vibration.
- Preload & Matched Arrangements: The bearing is supplied with a preload and is intended for use as a single bearing in a matched arrangement, simplifying installation and ensuring immediate, precise performance.
7226 ACD/P4A Bearing Typical Application Areas
This high-precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles (milling, grinding, and turning centers)
- High-Frequency Motors and Spindles
- Precision Gearboxes
- Medical and Laboratory Equipment
- Robotics and Automation Systems
