6204 NR Bearing Product Overview & Core Advantages
The 6204 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable operation. Its key distinguishing feature is the snap ring groove and fitted snap ring on the outer ring, which provides secure axial location within a housing, simplifying assembly and reducing total assembly costs. Manufactured with high-precision P0 tolerance and standard CN radial internal clearance, this open-type bearing is a versatile and cost-effective solution for a wide range of industrial applications requiring robust performance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6204 | Standard bearing series designation, indicating a metric, single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width. |
| NR | Signifies that the bearing has a snap ring groove on the outer ring and is supplied with a snap ring fitted. This feature aids in axial positioning. |
6204 NR Bearing Structural Features & Performance Benefits
- Snap Ring Locating Feature: The integrated snap ring groove and supplied snap ring (52.7 mm OD, 1.12 mm width) enable secure axial location, preventing creep in the housing. This eliminates the need for complex housing shoulders or end caps, reducing design complexity and manufacturing costs.
- High Load Capacity: The deep groove raceway and optimized geometry provide a high radial dynamic load rating of 3035 lbf and a radial static load rating of 1472 lbf, ensuring durability under significant radial loads.
- Robust Construction: Components are manufactured from chrome steel for rings and balls, and a stainless steel cage, offering excellent strength, wear resistance, and corrosion protection for the cage.
- Precision Operation: Built to P0 tolerance class and standard CN clearance, this bearing ensures smooth, low-vibration, and reliable performance in general industrial applications.
- High-Speed Capability: With a limiting speed of 20,000 rpm, it is suitable for applications requiring high rotational velocities.
6204 NR Bearing Typical Application Areas
This bearing is ideally suited for applications where secure axial location is critical and space is limited. Common uses include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Conveyor System Pulleys
- Agricultural Machinery
- Material Handling Equipment
