6204-2RS1/C3 GJN Bearing Product Overview & Core Advantages
The 6204-2RS1/C3 GJN is a metric 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 offering robust operational stability. The bearing features integral contact seals (2RS1) for superior contamination protection and is supplied with a high-quality grease pre-lubrication (GJN), making it a ready-to-install, low-maintenance solution. With a C3 radial internal clearance, it is optimally suited for applications involving thermal expansion or heavy loads, ensuring consistent performance and extended service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6204 | Basic bearing series and size designation (20mm bore, 47mm OD, 14mm width). |
| 2RS1 | Bearing with rubber contact seals on both sides. Provides excellent protection against dust and moisture ingress. |
| C3 | Radial internal clearance greater than Normal (CN). Ideal for applications with expected thermal expansion or heavy interference fits. |
| GJN | The bearing is pre-lubricated with a high-quality, lithium soap base grease with a temperature range of -30°C to +120°C. |
6204-2RS1/C3 GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. It is rated for a dynamic load capacity of 2878 lbf and a static load capacity of 1495 lbf, ensuring reliable performance under significant radial loads.
- Enhanced Sealing & Lubrication: The 2RS1 rubber contact seals effectively shield the internal components from contaminants, while the GJN grease pre-lubrication provides long-term, maintenance-free operation within a wide temperature range (-30°C to 120°C).
- Optimized Internal Clearance: The C3 clearance is a critical feature that accommodates shaft expansion and heavy interference fits, preventing premature failure due to excessive preload and ensuring smooth operation.
- Precision & Speed: Built to ABEC 1 | ISO P0 tolerance standards, it offers reliable precision for general industrial use. The limiting speed of 15,000 rpm makes it suitable for a wide range of high-speed applications.
