3213 A-2Z Bearing Product Overview & Core Advantages
The 3213 A-2Z is a double row angular contact ball bearing engineered for applications requiring high rigidity and the ability to handle combined loads. This precision bearing is designed to simultaneously support substantial radial loads and bidirectional axial loads, making it an ideal solution for compact arrangements demanding high reliability and performance. Its pre-lubricated and shielded design ensures long-term, maintenance-free operation in demanding environments.
3213 A-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 3213 | Standard bore diameter (65 mm), outside diameter (120 mm), and width (38.1 mm) | Defines the core bearing dimensions for interchangeability. |
| A | Contact angle of 30 degrees | Optimized for carrying high axial loads. |
| 2Z | Shields on both sides | Provides effective protection against contaminants while retaining lubricant, enabling a maintenance-free design. |
3213 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 significant combined loads (both radial and bidirectional axial forces) with minimal deflection. This makes it exceptionally stable under complex loading conditions.
Optimized for Performance: The stainless steel cage ensures smooth operation and is suitable for higher speeds. Combined with the P6 (ABEC-3) tolerance class, this bearing delivers the running accuracy required for precision applications.
Long Service Life & Reliability: The 2Z shields protect the internal components from dust and debris, while the factory-applied lubrication is suitable for a wide temperature range of -30°C to 110°C. This sealed and lubricated-for-life construction minimizes maintenance needs and extends service intervals.
3213 A-2Z Bearing Typical Application Areas
The 3213 A-2Z is ideally suited for a wide range of industrial machinery where high rigidity and combined load capacity are critical. Key application areas include:
- Machine Tool Spindles
- Industrial Gearboxes
- Pumps and Compressors
- Material Handling Equipment
- Precision Agricultural Machinery
