1208 ETN9/W64 Bearing Product Overview & Core Advantages
The 1208 ETN9/W64 is a double row angular contact ball bearing designed for applications requiring high precision and reliable performance. This metric bearing features an open design and is pre-lubricated for immediate use. Its double row construction enables it to support significant combined loads (both radial and axial) while maintaining high rigidity. The optimized internal geometry and nylon cage contribute to its smooth operation and suitability for demanding industrial environments where precision and durability are paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1208 | Standard bearing designation (40mm bore, 80mm OD) |
| E | Optimized internal design for enhanced load capacity |
| TN9 | Nylon cage, glass fiber reinforced, suitable for high speeds |
| W64 | Pre-lubricated with specific high-performance grease |
1208 ETN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness and enables the bearing to handle substantial radial dynamic loads (4478 lbf) and static loads (1564 lbf) simultaneously.
High-Speed Performance: The TN9 nylon cage ensures stable operation at elevated speeds, contributing to the bearing's limiting speed of 11,000 rpm. The lightweight cage reduces centrifugal forces and maintains alignment.
Precision & Reliability: Manufactured from chrome steel for both rings and balls, the bearing offers consistent performance and long service life. The standard CN radial internal clearance ensures optimal fit and performance in most applications.
Ready-to-Use Lubrication: Pre-lubricated with W64 grease, the bearing is immediately operational and maintains effective lubrication within its specified temperature range of -30°C to 110°C.
