3212 A-2Z Bearing Product Overview & Core Advantages
The 3212 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 an ideal, compact solution for high-reliability machinery. Its pre-lubricated and shielded design ensures long-term operational integrity with minimal maintenance.
3212 A-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 3212 | Standard bearing series designation, indicating bearing dimensions (60mm bore, 110mm OD). | Defines the core geometry and interchangeability. |
| A | Contact angle of 30°. | Optimized for carrying high axial loads. |
| 2Z | Shields on both sides. | Provides effective protection against contaminants while retaining lubrication, enabling maintenance-free operation. |
3212 A-2Z Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to handle heavy combined loads with minimal deflection. The optimized bearing dimensions and 30° contact angle contribute to its high radial dynamic load rating of 16,875 lbf and radial static load rating of 14,400 lbf.
Optimized for Performance: The stainless steel cage ensures stability and durability, contributing to smooth operation. With a limiting speed of 5,600 rpm, it is suitable for a wide range of high-speed applications.
Long Service Life & Reliability: The combination of chrome steel rings and balls, factory-applied lubrication, and Z-shields creates a sealed, long-life system. The P6 (ABEC-3) tolerance class guarantees precision and consistent performance in demanding environments.
3212 A-2Z Bearing Typical Application Areas
The 3212 A-2Z is ideally suited for a variety of industrial applications where reliability under combined loads is critical. Key sectors include:
- Industrial Gearboxes and Transmissions
- Pumps and Compressors
