6305-2RS1/C3 GJN Bearing Product Overview & Core Advantages
The 6305-2RS1/C3 GJN is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while accommodating moderate axial loads in both directions. The combination of sealed construction and C3 radial internal clearance makes it exceptionally suitable for applications with thermal expansion or where higher operational speeds are required, ensuring consistent performance and extended service life.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning |
|---|---|
| 6305 | Standard designation for a medium series, single row deep groove ball bearing with a 25mm bore. |
| 2RS1 | Bearing is fitted with contact seals on both sides, providing excellent protection against contaminant ingress and grease leakage. |
| C3 | Specifies a greater than normal radial internal clearance. This is ideal for applications with shaft misalignment, high speeds, or where operational heat generation is a factor. |
| GJN | Indicates the bearing is pre-lubricated with a specific, high-quality polyurea grease, offering a wide operating temperature range and long-term lubrication. |
6305-2RS1/C3 GJN Bearing Structural Features & Performance Benefits
Optimized Sealing & Lubrication: The 2RS1 double-contact seals effectively shield the bearing's interior from dust, moisture, and other contaminants, while the GJN grease ensures smooth operation across a wide temperature range (-30°C to 120°C), resulting in a maintenance-free design for the majority of its service life.
Enhanced Operational Capability: The C3 radial clearance provides operational stability in environments prone to thermal expansion, preventing binding and reducing friction at elevated temperatures. This contributes to a high limiting speed of 11,000 rpm.
Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 4631 lbf, making it capable of withstanding significant radial stresses.
Precision & Consistency: Produced to ABEC 1 | ISO P0 tolerance class, it guarantees reliable and predictable performance, which is critical for smooth-running machinery.
6305-2RS1/C3 GJN Bearing Typical Application Areas
