6205NR/QE6 Bearing Product Overview & Core Advantages
The 6205NR/QE6 is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and precise operation. A key distinguishing feature is the snap ring groove on its outer ring, which facilitates secure axial positioning within a housing, simplifying assembly and enhancing system rigidity. Manufactured to ABEC 1 | ISO P0 tolerance standards, this open-type bearing offers an excellent balance of performance, durability, and value for a wide range of industrial uses.
6205NR/QE6 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6205 | Standard designation for a single row deep groove ball bearing with a 25mm bore and 52mm OD. |
| NR | Signifies a snap ring groove on the outer ring. This feature allows for secure axial location. |
| QE6 | Indicates a specific radial internal clearance group, corresponding to the CN value in the specifications, which is the normal clearance for general applications. |
6205NR/QE6 Bearing Structural Features & Performance Benefits
- Snap Ring Groove for Enhanced Rigidity: The NR designation means the bearing is equipped with a groove for a snap ring. This allows for a simplified, compact housing design while providing secure axial location, which increases the overall system rigidity and prevents creeping.
- Robust Load Capacity: The deep groove raceway and high-quality chrome steel construction enable it to carry significant radial dynamic loads (up to 3147 lbf) and moderate axial loads in both directions.
- Optimized for Standard Speeds: With a limiting speed of 13,000 rpm, this bearing is suitable for a wide array of motor and drive applications. The CN clearance provides an optimal balance for general operating conditions.
- Versatile & Ready-to-Install: As an open bearing, it offers flexibility for the user to apply the specific lubricant required for the application. Its standard ABEC 1 precision ensures consistent and reliable performance.
6205NR/QE6 Bearing Typical Application Areas
This bearing is ideally suited for applications where secure axial location and reliable radial load support are critical. Common uses include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Agricultural Machinery
- Material Handling Equipment
