1212 ETN9/W64 Bearing Product Overview & Core Advantages
The 1212 ETN9/W64 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing features an open design and is pre-lubricated, offering a robust solution for handling significant combined loads (radial and axial) simultaneously. Its compact bearing dimensions (60mm bore, 110mm OD, 22mm width) and high rigidity make it ideal for applications requiring high reliability and precision in a constrained space.
1212 ETN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| E | Optimized internal design | Enhanced load capacity and performance. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced | Reduced friction, suitable for high-speed operation and offering good acceleration characteristics. |
| W64 | Bearing is pre-lubricated with a specific grease | Ensures immediate operation and provides long-term lubrication, reducing maintenance needs. |
1212 ETN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to support substantial radial loads and bidirectional axial loads simultaneously, making it highly effective for combined load conditions.
High-Speed Performance: The lightweight and robust TN9 nylon cage minimizes centrifugal forces and friction, contributing directly to the bearing's high limiting speed of 8,000 rpm. The pre-lubrication (W64) ensures optimal performance at these speeds.
Precision & Durability: Manufactured from chrome steel for both rings and balls, this bearing ensures high durability and consistent performance. The standard CN radial internal clearance is suited for a wide range of common industrial applications.
