1204 ETN9/W64 Bearing Product Overview & Core Advantages
The 1204 ETN9/W64 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance. This precision bearing features an open design and is pre-lubricated, making it suitable for handling significant combined loads (radial and axial) in both directions. Its compact dimensions and optimized internal geometry provide stable operation, making it an ideal choice for high-reliability industrial applications where space is constrained.
1204 ETN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| E | Optimized internal design for enhanced load capacity and reduced noise/vibration. |
| TN9 | Polyamide (Nylon) cage, glass fiber reinforced. Enables high-speed performance, low friction, and is suitable for high acceleration applications. |
| W64 | Indicates the bearing is pre-lubricated with a specific, high-performance grease suitable for the specified operating temperature range. |
1204 ETN9/W64 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior stiffness and enables the bearing to support substantial radial loads and bidirectional axial loads simultaneously, making it ideal for applications with combined loading.
- High-Speed Capability: The lightweight and robust TN9 nylon cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 20,000 rpm, ensuring stable operation at high rotational velocities.
- Pre-Lubricated for Longevity: Factory-applied lubrication (W64) ensures immediate operational readiness and provides long-term, maintenance-free service within the designated temperature range, reducing downtime and total cost of ownership.
- Precision Engineering: Manufactured from high-grade chrome steel with strict dimensional tolerances (e.g., bore diameter tolerance: -0.01mm to 0) for consistent performance and precise shaft positioning.
1204 ETN9/W64 Bearing Typical Application Areas
This bearing is widely used in various industrial sectors and equipment, including:
- Electric Motors and Small Spindles
- Pumps and Compressors
- Precision Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment
