3209 A-2Z Bearing Product Overview & Core Advantages
The 3209 A-2Z is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at simultaneously handling combined loads, including significant radial loads and bidirectional axial loads. Its compact bearing dimensions (45 mm bore, 85 mm OD, 30.2 mm width) and shielded construction make it ideal for space-constrained, high-rigidity applications demanding stable operation.
3209 A-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| A | Optimized contact angle (30°) | Enhanced axial load capacity and rigidity |
| 2Z | Shields on both sides | Effective contamination protection, retaining factory lubrication |
3209 A-2Z Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling stable performance under combined loads. With a dynamic load rating of 11700 lbf and static load rating of 9338 lbf, it handles demanding operational conditions.
- Optimized High-Speed Performance: The stainless steel cage ensures low friction and balanced operation, contributing to a limiting speed of 7,500 rpm. The optimized internal geometry minimizes heat generation at high speeds.
- Maintenance-Free Operation: Factory-applied lubrication and 2Z shields protect against contamination, ensuring long-term reliability without requiring re-lubrication within the specified temperature range (-30°C to 110°C).
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional controls (bore tolerance: -0.01mm to 0), ensuring consistent performance in precision applications.
