3208 A-2Z Bearing Product Overview & Core Advantages
The 3208 A-2Z is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and precision performance. This precision bearing is designed to simultaneously handle combined radial and bidirectional axial loads, making it ideal for compact arrangements where space is limited. With its shielded construction and factory-applied lubrication, it delivers reliable operation in demanding environments while maintaining P6 (ABEC-3) tolerance class accuracy.
3208 A-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 3208 | Basic bearing designation (40mm bore, 80mm OD) | Standard bearing dimensions for interchangeability |
| A | 30° contact angle design | Optimized for axial load capacity |
| 2Z | Double-sided steel shields | Contaminant protection with low friction |
3208 A-2Z Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, enabling precise shaft positioning and reduced deflection under combined loads.
Enhanced Load Capacity: With a radial dynamic load rating of 10,800 lbf and static rating of 8,212 lbf, this bearing effectively handles substantial radial and bidirectional axial loads simultaneously.
Optimized High-Speed Performance: The stainless steel cage ensures stable operation at limiting speeds up to 8,000 rpm, while the factory-applied lubrication reduces friction and heat generation.
Maintenance-Free Operation: The 2Z shielded design retains lubricant and excludes contaminants, providing long service life without relubrication across the temperature range of -30° to 110°C.
3208 A-2Z Bearing Typical Application Areas
- Machine Tool Spindles: Precision machining centers requiring high rigidity and accuracy
- Industrial Pumps & Compressors: Applications demanding reliable performance under combined loads
- Precision Gearboxes: Power transmission systems needing compact, high-capacity bearings
- Material Handling Equipment: Conveyor systems and automation machinery
- Medical & Laboratory Equipment: Devices requiring smooth, quiet operation with minimal maintenance
