4208 ATN9/W64 Bearing Product Overview & Core Advantages
The 4208 ATN9/W64 is a double row angular contact ball bearing engineered for high-performance applications requiring robust support for combined loads. Its metric design features a 40 mm bore and 80 mm outside diameter, delivering a compact and rigid solution. This bearing is characterized by its open construction, Nylon cage (TN9), and integrated Solid Oil lubrication (W64), making it suitable for applications demanding high rigidity and reliable operation within a specified temperature range. It is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and performance.
Model Code Breakdown
| Suffix Code | Technical Meaning | Significance & Advantage |
|---|---|---|
| A | Optimized internal design | Indicates a specific internal geometry that enhances load capacity and operational characteristics. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced | Provides low friction, excellent acceleration characteristics, and is ideal for high-speed operation. |
| W64 | Solid Oil lubrication | A polymer matrix saturated with oil, offering long-term lubrication, reduced maintenance, and protection in demanding environments. |
4208 ATN9/W64 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior radial and axial stiffness, enabling the bearing to effectively handle significant combined loads (radial and axial acting simultaneously).
- Optimized High-Speed Performance: The lightweight Nylon TN9 cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 13,000 rpm. This makes it a capable high-speed bearing.
- Maintenance-Free Operation: The integrated Solid Oil (W64) lubrication system ensures consistent performance and a long service life without the need for re-lubrication, reducing total cost of ownership.
- Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, guaranteeing reliable and predictable performance in a wide range of applications.
