6304-2RS1/C3W64 Bearing Product Overview & Core Advantages
The 6304-2RS1/C3W64 is a single row deep groove ball bearing designed for high reliability and robust performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads and moderate axial loads in both directions. The bearing features integrated seals and a factory-pre-filled solid oil lubricant, making it a maintenance-free solution ideal for applications requiring long service life and consistent operation within a wide temperature range.
6304-2RS1/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Basic bearing series, indicating a medium duty, single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. |
| 2RS1 | The bearing is equipped with two contact seals (one on each side), providing superior protection against contamination and retention of lubricant. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with thermal expansion or where interference fits are used. |
| W64 | Indicates the bearing is lubricated with Solid Oil, a polymer matrix saturated with oil. This provides lifelong lubrication, eliminates leakage, and is suitable for a wide operating temperature range. |
6304-2RS1/C3W64 Bearing Structural Features & Performance Benefits
- Sealed & Maintenance-Free Design: The 2RS1 contact seals effectively shield the bearing internals from dust, moisture, and other contaminants while retaining the solid oil lubricant. This combination eliminates the need for re-lubrication, reducing maintenance costs and downtime.
- Optimized Lubrication with Solid Oil: The W64 Solid Oil filling ensures consistent lubrication across the entire operating temperature range (-30°C to +120°C). It does not leak, drip, or harden, providing reliable performance in challenging environments and orientations.
- Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 3574 lbf and a static load rating of 1765 lbf, ensuring durability under significant radial loads.
- Stable Operation with C3 Clearance: The C3 radial internal clearance accommodates thermal expansion in the shaft and housing, preventing preload and ensuring smooth, low-vibration operation, particularly in applications with temperature fluctuations.
6304-2RS1/C3W64 Bearing Typical Application Areas
This versatile and reliable bearing is commonly specified in:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- Food Processing and Packaging Equipment (where its sealed, non-drip lubrication is a significant advantage)
