6205NR JEM/C3 Bearing Product Overview & Core Advantages
The 6205NR JEM/C3 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. Its key distinguishing feature is the snap ring groove on the outer ring, which simplifies axial positioning and reduces the need for complex housing designs. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable operation and excellent value. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring consistent performance under varying operational conditions.
Model Code Breakdown
| Code Segment | Technical Meaning |
| 6205 | Standard deep groove ball bearing series with 25mm bore, 52mm OD, 15mm width |
| NR | Snap ring groove on the outer ring for simplified axial location |
| JEM | Manufacturer's designation for specific manufacturing process |
| C3 | Greater than normal radial internal clearance for thermal expansion compensation |
6205NR JEM/C3 Bearing Structural Features & Performance Benefits
Deep Groove Design: The optimized raceway geometry enables the bearing to handle both radial loads and moderate axial loads in both directions, making it versatile for various mounting configurations.
Snap Ring Groove Advantage: The integrated snap ring groove provides secure axial positioning without requiring additional machining of the housing, reducing assembly time and costs while maintaining precise alignment.
Enhanced Thermal Performance: The C3 clearance accommodates thermal expansion in applications where operating temperatures vary significantly, preventing premature failure due to excessive preload.
High-Quality Materials: Constructed entirely from chrome steel for rings, balls, and cage, ensuring consistent hardness, wear resistance, and long service life under standard operating conditions.
6205NR JEM/C3 Bearing Typical Application Areas
The 6205NR JEM/C3 is widely used across multiple industries due to its reliable performance and mounting convenience:
- Electric Motors: Particularly in industrial motors where thermal expansion must be accommodated
- Gearboxes and Transmissions: Providing stable shaft support with simplified housing design
- Material Handling Equipment: Conveyor systems, pulleys, and rollers requiring secure axial location
- Agricultural Machinery: Implement drives and PTO shafts where environmental conditions vary
- Industrial Pumps and Fans: Applications with moderate speeds and combined loading conditions
