6408/C3W64 Bearing Product Overview & Core Advantages
The 6408/C3W64 is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels at handling primarily radial loads and offers high operational reliability. Its key advantages include a generous C3 radial internal clearance, which accommodates thermal expansion in applications with high operating temperatures or heavy loads, and its Soild Oil lubrication for consistent, long-term performance with minimal maintenance. Built to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution for a wide range of industrial machinery.
6408/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Benefit |
|---|---|---|
| 6408 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 40 mm bore, 110 mm OD, and 27 mm width. |
| /C3 | Radial Internal Clearance | Specifies a greater than normal clearance. Ideal for applications with shaft misalignment, high speeds, or where thermal expansion is a concern. |
| /W64 | Solid Oil Lubrication | Indicates the bearing is pre-lubricated with a polymer-based oil-saturated matrix. Provides excellent contamination resistance and is suitable for the specified temperature range. |
6408/C3W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing ensures high strength and durability. With a radial dynamic load rating of 1432 lbf and a static load rating of 8206 lbf, it is built to withstand significant operational stresses.
- Optimized for Thermal & Dynamic Conditions: The C3 clearance is a critical feature that prevents bearing seizure by allowing for expansion under thermal loads or from press-fits, contributing to reliable performance and extended service life.
- Maintenance-Free & Contamination Resistant Operation: The integrated Soild Oil lubrication (W64) eliminates the need for re-lubrication, prevents lubricant wash-out, and acts as a barrier against contaminants, making it ideal for sealed-for-life applications.
- Balanced High-Speed Performance: The combination of a chrome steel cage and optimized lubrication enables a limiting speed of 6,700 rpm, suitable for a wide range of high-speed industrial drives.
6408/C3W64 Bearing Typical Application Areas
