3207 A Bearing Product Overview & Core Advantages
The 3207 A is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at simultaneously handling combined radial and bidirectional axial loads. Its compact design and P6 (ABEC-3) tolerance class make it ideal for high-rigidity arrangements. The bearing comes pre-lubricated for immediate use and is constructed from high-grade chrome steel for durability and performance in demanding environments.
3207 A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Optimized internal design with a 30° contact angle for superior axial load capacity. |
| (No Seal Suffix) | Open design, allowing for custom lubrication schemes and high-speed operation. |
3207 A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide exceptional stiffness, enabling the bearing to support significant combined loads (radial and bidirectional axial loads) with minimal deflection.
- Precision & Speed: Manufactured to P6 tolerance class for precise running accuracy. The stainless steel cage ensures stability and contributes to the high limiting speed of 9,000 rpm.
- Durability & Compliance: Components made from chrome steel offer high fatigue resistance. The bearing is pre-lubricated for long service life and is compliant with ROHS and REACH environmental standards.
3207 A Bearing Typical Application Areas
This bearing is ideally suited for:
- Machine Tool Spindles
- Precision Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- High-performance Electric Motors
