6309/C3W64 Bearing Product Overview & Core Advantages
The 6309/C3W64 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric bearing features a C3 radial internal clearance and is pre-lubricated with Solid Oil, making it an ideal solution for applications requiring high reliability and minimal maintenance. Its robust construction from chrome steel ensures excellent durability and consistent operation under significant radial dynamic loads up to 11915 lbf.
6309/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications, reducing preload and friction |
| W64 | Solid Oil lubrication | Provides long-term lubrication, eliminates leakage, and enables maintenance-free operation |
6309/C3W64 Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry: The single row deep groove design with precision-ground raceways ensures smooth operation and efficient load distribution, contributing to the high radial dynamic load rating.
- Enhanced Thermal Stability: The C3 radial clearance is specifically selected for applications where operational heat generation causes shaft and housing expansion, preventing binding and ensuring consistent performance.
- Maintenance-Free Operation: The integrated Solid Oil polymer matrix acts as a permanent lubricant reservoir. It is immune to leakage, wash-out, and drying, making the bearing suitable for sealed-for-life applications and harsh environments.
- High-Speed Capability: The combination of a chrome steel cage, precision ABEC 1 | ISO P0 tolerances, and effective Solid Oil lubrication allows for a limiting speed of 6,700 rpm.
6309/C3W64 Bearing Typical Application Areas
This bearing is widely specified in industries and equipment where reliability and minimal maintenance are critical. Common applications include:
- Industrial Electric Motors and Gearboxes
- Material Handling Conveyors and Pulleys
- Agricultural Machinery (e.g., tractor wheels, harvesters)
- Pumps and Compressors
- Ventilation Fans and Blowers
