3200 A-2ZTN9/MT33 Bearing Product Overview & Core Advantages
The 3200 A-2ZTN9/MT33 is a metric double row angular contact ball bearing engineered for applications requiring high precision and reliability. This compact bearing excels at simultaneously handling combined radial and bidirectional axial loads, making it an ideal solution for space-constrained assemblies. Its shielded construction and factory-applied lubrication ensure long-term performance with minimal maintenance, operating effectively within a temperature range of -30°C to 110°C.
3200 A-2ZTN9/MT33 Bearing Model Code Explained, Specifications & Naming Convention
| 3200 | Basic bearing series designation |
| A | 30° contact angle optimized for axial load capacity |
| 2Z | Double-sided steel shields providing effective contamination protection |
| TN9 | Polyamide cage design enabling high-speed operation and reduced friction |
| MT33 | High-performance grease lubrication ensuring consistent operation across the specified temperature range |
3200 A-2ZTN9/MT33 Bearing Structural Features & Performance Benefits
High Rigidity: The double row design provides superior radial and axial stiffness, delivering stable performance under combined loading conditions.
Enhanced Load Capacity: With a radial dynamic load rating of 1712 lbf and static rating of 968 lbf, this bearing effectively manages both radial forces and bidirectional axial loads.
Optimized High-Speed Performance: The TN9 polymer cage reduces mass and friction, contributing to the bearing's limiting speed of 24,000 rpm while maintaining dimensional stability.
Maintenance-Free Operation: Factory-applied MT33 grease combined with double shields (2Z) creates a sealed environment that prevents lubricant leakage and contaminant ingress, extending service life.
