6221/C3W64F Bearing Product Overview & Core Advantages
The 6221/C3W64F is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. Its open design facilitates efficient heat dissipation, while the C3 radial internal clearance ensures optimal operation under varying thermal conditions. Pre-lubricated with Soild Oil, it offers long-term, maintenance-free service, making it a reliable and cost-effective solution for a wide range of machinery.
6221/C3W64F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6221 | Basic bearing designation indicating a single row deep groove ball bearing with a 105 mm bore and 190 mm outside diameter. |
| C3 | Specifies a greater than normal radial internal clearance, suitable for applications with significant thermal expansion or where interference fits are used. |
| W64F | Indicates the bearing is pre-lubricated with Soild Oil, a solid polymer-based lubricant that provides consistent performance and is resistant to wash-out. |
6221/C3W64F Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: Manufactured from chrome steel for both rings and balls, this bearing is built to withstand high radial dynamic and static loads. The single row deep groove raceway and robust chrome steel cage contribute to its structural integrity and stable operation under load.
- Optimized Internal Clearance: The C3 clearance is a key feature that prevents pre-loading and potential seizure in applications prone to thermal expansion, ensuring reliable performance and extended service life.
- Maintenance-Free Operation: The integration of Soild Oil lubrication eliminates the need for re-lubrication, reducing maintenance costs and preventing contamination. This solid lubricant performs consistently across the specified temperature range of -30°C to 120°C.
- Precision & Speed: Conforming to ABEC 1 | ISO P0 tolerance class, it offers dependable precision for general industrial use. The open seal type allows for a higher limiting speed by minimizing friction from contact seals.
6221/C3W64F Bearing Typical Application Areas
This versatile bearing is ideally suited for a multitude of industrial sectors and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Conveyors
- Agricultural Machinery
- Pumps and Fans
- General machinery requiring a reliable, maintenance-free radial bearing solution.
