1306 ETN9/W64 Bearing Product Overview & Core Advantages
The 1306 ETN9/W64 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at simultaneously handling combined loads, including significant radial loads and bidirectional axial loads. Its compact design, featuring a 30 mm bore and 72 mm outside diameter, offers a space-saving solution without compromising performance. The bearing comes pre-lubricated and utilizes a nylon cage (ETN9), making it suitable for high-speed operation up to 13,000 rpm, while its CN radial internal clearance ensures optimal performance in a wide range of applications.
1306 ETN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Basic bearing designation indicating the bearing size (30mm bore, 72mm OD, 19mm width) |
| E | Optimized internal design for enhanced load capacity |
| TN9 | Nylon cage, glass fiber reinforced, suitable for high speeds and offering quiet operation |
| W64 | Bearing is pre-lubricated with a specific grease suitable for the specified temperature range |
1306 ETN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to support substantial combined radial and axial loads in both directions, making it ideal for applications with complex loading conditions.
High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces and friction, contributing directly to the high limiting speed of 13,000 rpm. The pre-applied W64 grease lubrication ensures consistent performance and reduced wear at these elevated speeds.
Precision & Reliability: Manufactured from chrome steel for both rings and balls, this bearing guarantees durability and long service life. The standard CN radial internal clearance is suited for most common operating conditions, providing a balance between temperature management and running accuracy.
