3309 A-2Z Bearing Product Overview & Core Advantages
The 3309 A-2Z is a double row angular contact ball bearing designed for applications requiring high rigidity and the ability to handle combined loads. Its compact design integrates two rows of balls, enabling it to support significant radial loads and bidirectional axial loads simultaneously. Manufactured to a P6 (ABEC-3) tolerance class, it is a precision bearing ideal for high-reliability machinery. The inclusion of shields and factory-applied lubrication ensures long-term performance with minimal maintenance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 3309 | Standard bore diameter code (45 mm) and series designation. |
| A | Signifies a 30° contact angle, optimized for carrying substantial axial loads. |
| 2Z | Indicates the bearing is shielded on both sides. This provides effective protection against contaminants while retaining lubricant, contributing to its maintenance-free characteristics. |
3309 A-2Z Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to handle high combined radial and axial loads. The specified load points ensure stable operation under complex loading conditions.
- Precision Performance: Built to P6 tolerance with a stainless steel cage, this bearing ensures smooth running and precise rotational accuracy, making it suitable for high-speed applications up to 6,700 rpm.
- Extended Service Life & Reliability: The combination of chrome steel rings and balls, along with shielded seals and pre-lubrication, protects against contamination and reduces friction, resulting in long-lasting, reliable performance with minimal maintenance requirements.
3309 A-2Z Bearing Typical Application Areas
The 3309 A-2Z is engineered for demanding applications across various industries, including:
- Industrial Gearboxes and Transmissions
