3307 A-2Z Bearing Product Overview & Core Advantages
The 3307 A-2Z is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance. This precision bearing is capable of simultaneously supporting combined loads (radial and bidirectional axial loads) in a compact design. Its shielded construction and pre-lubrication ensure long-term, maintenance-free operation, making it an ideal choice for demanding industrial environments where space constraints and operational reliability are critical.
3307 A-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| A | Contact angle optimized for axial load capacity |
| 2Z | Non-contact shields on both sides providing effective contamination protection while maintaining high-speed capability |
3307 A-2Z Bearing Structural Features & Performance Benefits
- High Rigidity: The double row design provides superior radial and axial stiffness, ensuring stable shaft positioning under combined loads.
- Load Capacity: Engineered to handle significant radial dynamic loads (12,150 lbf) and static loads (8,550 lbf) while accommodating bidirectional axial forces.
- Speed Performance: The stainless steel cage and optimized internal geometry enable reliable operation at limiting speeds up to 8,500 rpm.
- Maintenance-Free Operation: Both side shields (2Z) retain factory-applied lubricant and protect against contamination, extending service intervals in various operating conditions.
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class for consistent performance in precision applications.
