3207 A-2Z Bearing Product Overview & Core Advantages
The 3207 A-2Z is a double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined loads. This precision bearing is designed to simultaneously accommodate significant radial loads and axial loads in both directions, making it a compact and efficient solution for demanding machinery. Its shielded construction and factory-applied lubrication ensure long-term, maintenance-free operation, ideal for high-reliability scenarios.
3207 A-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 3207 | Standard bore diameter (35 mm), outside diameter (72 mm), and width (27 mm) | Defines the core bearing dimensions for compatibility and interchangeability. |
| A | Contact angle of 30° | Optimized for carrying high axial loads. |
| 2Z | Shielded on both sides | Provides effective protection against contaminants while retaining lubricant, enabling maintenance-free operation. |
3207 A-2Z Bearing Structural Features & Performance Benefits
High Rigidity: The double row design provides superior radial and axial stiffness, ensuring stable shaft support and minimizing deflection under heavy combined loads.
Load Capacity: Engineered to handle significant radial loads (dynamic: 9112 lbf, static: 6750 lbf) and bidirectional axial loads simultaneously, thanks to its optimized internal geometry and 30° contact angle.
Speed Performance: With a limiting speed of 9,000 rpm, this bearing is suitable for high-speed applications. The stainless steel cage contributes to smooth operation at high rotational velocities.
Durability & Maintenance: The 2Z shields protect the bearing from dust and debris, while the pre-applied lubricant ensures consistent performance across a wide temperature range (-30°C to 110°C), offering a long service life with minimal maintenance.
3207 A-2Z Bearing Typical Application Areas
The 3207 A-2Z is ideally suited for a variety of industrial applications, including:
- Machine Tool Spindles
- Industrial Pumps and Compressors
- Gearboxes and Transmission Systems
- Precision Agricultural Machinery
- Material Handling Equipment
