6309-2RS2/C3WT Bearing Product Overview & Core Advantages
The 6309-2RS2/C3 is a sealed single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric bearing features integrated rubber seals (2RS2) on both sides, providing superior protection against contaminants and moisture retention. Engineered with a C3 radial internal clearance, it is ideally suited for applications involving thermal expansion or where interference fits are used. Its robust construction from chrome steel ensures high durability and consistent performance under significant radial dynamic loads up to 11915 lbf.
6309-2RS2/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6309 | Standard series code denoting a medium-duty, single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width. | Defines the core bearing dimensions and series for interchangeability. |
| 2RS2 | Contact rubber seals on both sides of the bearing. | Provides effective sealing against dust and moisture, extending service life in contaminated environments. |
| C3 | Radial internal clearance greater than normal (CN). | Accommodates thermal expansion from high speeds or tight fits, preventing premature failure due to excessive preload. |
6309-2RS2/C3WT Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and high-quality chrome steel construction provide high radial load capacity and reliable operation.
- Superior Sealing with 2RS2: The double-lipped contact rubber seals offer excellent defense against contaminants and retain lubricant effectively, making the bearing suitable for harsh conditions and contributing to low maintenance requirements.
- Optimized Internal Clearance (C3): The C3 clearance is a critical feature for applications with expected temperature variations or where shaft and housing fits result in a reduction of internal clearance, ensuring stable performance and preventing binding.
- Standard Precision (ABEC 1 | ISO P0): This tolerance class provides a cost-effective solution for a wide range of general industrial applications where ultra-high precision is not the primary driver.
6309-2RS2/C3WT Bearing Typical Application Areas
