6307/C3W64 Bearing Product Overview & Core Advantages
The 6307/C3W64 is a single row deep groove ball bearing designed for exceptional 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 for thermal expansion management and Solid Oil lubrication for long-term, maintenance-free operation. Built with chrome steel components and manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a robust and cost-effective solution for a wide range of industrial machinery.
6307/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6307 | Standard designation for a single row deep groove ball bearing with a 35mm bore, 80mm OD, and 21mm width. | Defines the core bearing dimensions and type. |
| /C3 | Specifies a radial internal clearance greater than normal (C3 group). | Accommodates thermal expansion in applications with high operating temperatures or tight fits, preventing premature failure. |
| /W64 | Indicates the bearing is lubricated with Solid Oil. | Provides a sealed-for-life lubrication system, eliminating relubrication needs and offering excellent resistance to oil washout and contamination. |
6307/C3W64 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Capacity Design: The optimized raceway geometry enables the bearing to handle significant radial dynamic load ratings (7509 lbf) and radial static load ratings (4339 lbf), ensuring durability under heavy loads.
- C3 Internal Clearance: This specific clearance group is engineered for applications where shaft and housing fits, or operational heat, cause a reduction in internal clearance. It ensures smooth, uninterrupted operation and extends bearing service life.
- Solid Oil Lubrication (W64): The bearing is filled with a polymer matrix saturated with lubricating oil. This technology offers superior performance in environments where conventional grease may leak, be washed out, or where maintenance access is limited, supporting a limiting speed of 8,500 rpm.
- Chrome Steel Construction: All critical components—rings, balls, and cage—are manufactured from high-grade chrome steel, providing high hardness, wear resistance, and a long operational lifespan.
6307/C3W64 Bearing Typical Application Areas
This bearing is ideally suited for a broad spectrum of industrial equipment, including:
- Electric Motors and Gearboxes
- Material Handling Conveyors
- Industrial Fans and Blowers
- Agricultural Machinery
- Pumps and Compressors
