1205 ETN9/W64 Bearing Product Overview & Core Advantages
The 1205 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 without integral seals, making it suitable for systems where external sealing is provided. Its double row construction provides superior rigidity and enables it to accommodate combined loads—significant radial loads alongside axial loads in both directions. With a limiting speed of 18,000 rpm and optimized internal geometry, it delivers exceptional high-speed performance. Pre-lubricated for immediate use, this bearing offers a compact solution for space-constrained, high-demand applications.
1205 ETN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Significance |
|---|---|---|
| E | Optimized Internal Design | Enhanced load capacity and reduced operating noise. |
| TN9 | Nylon Cage, Glass Fiber Reinforced | Lightweight cage for high-speed operation, excellent acceleration characteristics, and good compatibility with lubricants. |
| W64 | Pre-lubricated with a specific grease | Provides immediate lubrication for the initial operation, simplifying installation and reducing maintenance needs. |
1205 ETN9/W64 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design, combined with the optimized internal geometry (suffix E), provides significantly increased rigidity and enables the bearing to support substantial radial dynamic loads (3218 lbf) and static loads (900 lbf), as well as bidirectional axial loads.
- Superior High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces, reduces friction, and ensures stable operation at the high limiting speed of 18,000 rpm.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and wear resistance. The standard CN radial internal clearance ensures reliable performance under normal operating conditions.
- Ready-to-Install Convenience: The bearing is pre-lubricated (W64), making it immediately operational upon installation and reducing initial setup complexity.
