6205-2RS1/C3 GJN Bearing Product Overview & Core Advantages
The 6205-2RS1/C3 GJN is a metric single row deep groove ball bearing engineered for high reliability and performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while its sealed construction ensures long-term operational integrity. Featuring a C3 radial internal clearance, this bearing is particularly suited for applications with elevated operational temperatures or where interference fits are used, preventing excessive preload and ensuring smooth rotation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a robust balance of precision and value, making it an excellent choice for general industrial machinery requiring dependable performance.
6205-2RS1/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 2RS1 | Contact seals on both sides, made from NBR rubber. | Provides effective contamination exclusion and grease retention, enhancing bearing life in dirty environments. |
| C3 | Radial internal clearance greater than Normal (CN) group. | Accommodates thermal expansion, ideal for applications with high temperatures or tight fits, preventing binding. |
| GJN | Pre-lubricated with a specific, high-quality polyurea grease. | Offers a wide operating temperature range (-30°C to +120°C) and contributes to maintenance-free operation. |
6205-2RS1/C3 GJN Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and continuous shoulder design enable the bearing to support significant radial dynamic load ratings (up to 3147 lbf) and moderate axial loads in both directions.
- Sealed for Life & Reliability: The integrated 2RS1 contact seals effectively shield the internal components from contaminants like dust and moisture, while securely retaining the pre-applied GJN lubricant. This creates a maintenance-free solution that extends service intervals and improves machine uptime.
- Optimized for Thermal Stability: The C3 internal clearance is a critical feature that provides extra space between the rolling elements and raceways. This prevents thermal expansion from causing excessive preload and friction, ensuring stable performance and a high limiting speed of 13,000 rpm even under thermally challenging conditions.
- Precision Chrome Steel Construction: All core components—rings, balls, and cage—are manufactured from high-grade chrome steel, ensuring high hardness, wear resistance, and consistent performance under load.
6205-2RS1/C3 GJN Bearing Typical Application Areas
