6308-2RS1/C4GJN Bearing Product Overview & Core Advantages
The 6308-2RS1/C4GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering operational reliability through its integrated sealing. The bearing features a C4 radial internal clearance, making it suitable for applications with specific thermal expansion requirements or where interference fits are used. Manufactured from high-grade chrome steel and built to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and long service life, making it an excellent choice for general industrial machinery requiring a sealed and reliable precision bearing.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Basic series designation for a medium-duty, single row deep groove ball bearing with a 40mm bore. |
| 2RS1 | Indicates the bearing is fitted with two rubber contact seals (RS1 type) on both sides. This provides superior protection against contaminants and retains lubricant. |
| C4 | Specifies a greater than normal radial internal clearance. This is critical for applications involving thermal expansion, heavy interference fits, or where operational temperatures vary significantly. |
| GJN | This suffix is not a standard universal code. It is strongly recommended to consult the manufacturer's documentation for the specific meaning, as it may refer to a special grease filling, a proprietary cage design, or another manufacturer-specific feature. |
6308-2RS1/C4GJN Bearing Structural Features & Performance Benefits
- Robust Sealing for Contaminant Exclusion: The 2RS1 rubber contact seals effectively shield the internal components from dust, moisture, and other contaminants. This significantly enhances bearing life in harsh environments and contributes to its maintenance-free characteristics by retaining lubricant.
- Optimized Internal Geometry: The deep groove raceway and high-precision chrome steel balls ensure smooth operation and efficient radial load distribution, minimizing friction and heat generation.
- Controlled Internal Clearance (C4): The C4 radial clearance provides operational stability in applications prone to shaft expansion or heavy press fits, preventing excessive preload and potential seizure.
- High-Quality Material Construction: All core components, including rings, balls, and cage, are manufactured from chrome steel, offering high strength, durability, and resistance to wear.
- Standardized Precision: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring reliable interchangeability and consistent performance for a wide range of industrial applications.
