6305-2RS1/C3GJN Bearing Product Overview & Core Advantages
The 6305-2RS1/C3GJN is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing features integral contact seals (2RS1) for effective contamination exclusion and is pre-lubricated for long service life. Engineered with a C3 radial internal clearance, it is well-suited for applications where thermal expansion is a concern. Its robust construction from chrome steel provides excellent durability and a high radial dynamic load rating of 4631 lbf, making it a versatile and dependable choice for industrial machinery.
6305-2RS1/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6305 | Basic bearing series; Deep Groove Ball Bearing with 25mm bore, 62mm OD, 17mm width. |
| 2RS1 | Bearing is fitted with two rubber contact seals on both sides, providing superior protection against contaminants and retaining lubricant. |
| C3 | Specifies a greater than normal radial internal clearance. Ideal for applications with expected thermal expansion or where interference fits are used. |
| GJN | Indicates the use of a specific, high-quality polyurea grease filling. This lubricant offers a wide temperature range and extended lubrication life. |
6305-2RS1/C3GJN Bearing Structural Features & Performance Benefits
- Sealed for Protection and Longevity: The 2RS1 rubber contact seals effectively shield the internal components from dust, moisture, and other contaminants. Combined with the pre-applied GJN grease, this creates a maintenance-free solution for the bearing's operational life in many applications.
- Optimized Internal Clearance: The C3 radial clearance provides operational stability in environments with significant temperature fluctuations or where press-fits are employed, preventing premature failure due to excessive preload.
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high radial dynamic load rating, ensuring reliable performance under substantial radial loads.
- Precision and Consistency: Produced to ABEC 1 | ISO P0 tolerance class, this bearing guarantees consistent dimensional accuracy and smooth running for a wide range of general industrial applications.
