6204-2RS2/C3GJN Bearing Product Overview & Core Advantages
The 6204-2RS2/C3GJN is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its compact design, combined with a C3 radial internal clearance, makes it suitable for applications with thermal expansion or where precise shaft fits are required. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a robust balance of performance and value for high-volume industrial use.
6204-2RS2/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6204 | Standard deep groove ball bearing series with 20mm bore, 47mm OD, 14mm width | Defines basic dimensions and bearing type |
| 2RS2 | Double-sided contact seals with nitrile rubber (NBR) | Provides effective contamination protection and grease retention |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits |
| GJN | Standard grease filling (typically lithium soap-based) | Ensures immediate operation and extended service life |
6204-2RS2/C3GJN Bearing Structural Features & Performance Benefits
This bearing's performance stems from its optimized design: The single row deep groove raceway provides excellent radial load capacity (2878 lbf dynamic, 1495 lbf static). The double-sided contact seals (2RS2) create an effective barrier against contaminants while retaining lubrication, making the bearing maintenance-free for most applications. The C3 radial clearance accommodates shaft expansion and tight fitting conditions, reducing the risk of premature failure. All components are manufactured from chrome steel, ensuring consistent hardness and durability. The combination of precision manufacturing and effective sealing enables operation at speeds up to 15,000 rpm while maintaining reliability across a wide temperature range (-30° to 120°C).
