6405/W64 Bearing Product Overview & Core Advantages
The 6405/W64 is a metric single row deep groove ball bearing engineered for exceptional performance in demanding radial load applications. Its open design facilitates high-speed operation, while the integrated Soild Oil lubrication ensures long-term, maintenance-free service. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable precision and is an ideal choice for applications requiring a robust, cost-effective solution with a consistent temperature range of -30° to 120°C.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6405 | Standard designation for a single row deep groove ball bearing with a 25mm bore and 80mm outside diameter. |
| W64 | Indicates the bearing is pre-lubricated with Soild Oil, a polymer-based lubricant that is permanently retained. |
6405/W64 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open seal type minimizes friction and heat generation, enabling a high limiting speed of 9,000 rpm. The precision chrome steel cage maintains ball alignment and stability at these velocities.
- Robust Load Capacity: The single row deep groove raceway is optimized to handle significant radial dynamic load ratings of 8048 lbf and radial static load ratings of 4339 lbf.
- Maintenance-Free Operation: The Soild Oil lubrication is sealed within the bearing, eliminating the need for re-lubrication and preventing contamination, which is critical for long service life.
- Precision & Consistency: Manufactured from high-grade chrome steel for both rings and balls, and held to ABEC 1 | ISO P0 tolerances, this bearing ensures reliable performance and dimensional stability.
6405/W64 Bearing Typical Application Areas
This bearing is widely used in various industrial sectors due to its balance of speed, load capacity, and maintenance-free design. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
