6309-2RS1/C3W64F Bearing Product Overview & Core Advantages
The 6309-2RS1/C3W64F is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. Engineered to handle primarily radial loads with high efficiency, this sealed bearing features Solid Oil lubrication and an optimized C3 radial internal clearance for stable operation across a wide temperature range. Its robust construction from chrome steel ensures long service life, making it an ideal choice for applications requiring maintenance-free operation and consistent performance.
6309-2RS1/C3W64F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6309 | Basic bearing series, indicating a medium-duty, single row deep groove ball bearing with a 45mm bore. |
| 2RS1 | Bearing is equipped with two contact seals (one on each side), providing superior protection against contaminant ingress. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with thermal expansion or where fits result in clearance reduction. |
| W64F | Indicates the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with oil, offering long-term lubrication and resistance to washout. |
6309-2RS1/C3W64F Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and high-quality chrome steel construction provide excellent radial load capacity and operational stability.
- Superior Sealing with 2RS1: The two-contact rubber seals effectively retain lubrication and exclude contaminants like dust and moisture, significantly extending bearing life in harsh environments.
- Optimized Internal Clearance (C3): The C3 clearance accommodates differential thermal expansion between the shaft and housing, preventing preload and ensuring smooth operation under varying thermal conditions.
- Advanced Solid Oil Lubrication (W64F): This technology eliminates oil leakage, is resistant to centrifugal forces, and provides a consistent lubricating film, enabling maintenance-free operation and a high limiting speed of 6,700 rpm.
- Precision Manufacturing (ABEC 1 | ISO P0): Manufactured to standard precision tolerances, ensuring reliable and predictable performance for a wide range of industrial applications.
