3212 A Bearing Product Overview & Core Advantages
The 3212 A is a double row angular contact ball bearing engineered for applications requiring high rigidity and precision. This precision bearing is designed to accommodate combined loads—simultaneously handling significant radial loads and bidirectional axial loads. Its compact double-row design offers a robust and space-saving solution, making it ideal for high-reliability machinery. Manufactured to a P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy and consistent performance in demanding operational environments.
3212 A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Indicates a 30° contact angle, optimized for carrying high axial loads. |
| Open | No seals or shields, allowing for higher speeds and facilitating custom lubrication schemes. |
3212 A Bearing Structural Features & Performance Benefits
- High Rigidity: The double row ball complement and robust construction provide superior stiffness, minimizing deflection under load for enhanced positional accuracy.
- Superior Load Capacity: Engineered to handle combined loads effectively. The 30° contact angle is specifically designed for high axial load capacity in both directions.
- Optimized for Performance: The stainless steel cage ensures durability and stable operation at the limiting speed of 5,600 rpm. The open design reduces friction and heat generation.
- Precision Engineering: Manufactured to P6 tolerance standards, guaranteeing tight bearing dimensions and consistent internal geometry for smooth, quiet, and precise rotation.
3212 A Bearing Typical Application Areas
This bearing is ideally suited for:
- Machine Tool Spindles
- Gearboxes and Transmissions
- Industrial Pumps and Compressors
- Precision Agricultural and Construction Equipment
