206 NR Bearing Product Overview & Core Advantages
The 206 NR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable performance in demanding applications. Its key distinguishing feature is the snap ring on the outer ring, which provides secure axial location within a housing, simplifying assembly and reducing overall design space. Manufactured with precision tolerances (P0 class) and high-grade chrome steel components, this bearing delivers consistent operation and long service life. It is an open-type bearing, making it suitable for systems where external sealing is provided or specific lubrication regimes are required.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 206 | Standard bearing series designation, indicating the bearing dimensions (30mm bore, 62mm OD, 16mm width). |
| NR | Signifies a snap ring (fitted) on the outer ring. This groove and ring assembly facilitates secure mounting and positioning. |
206 NR Bearing Structural Features & Performance Benefits
- Snap Ring for Simplified Assembly: The integrated snap ring eliminates the need for complex housing shoulders or end caps, reducing part count, assembly time, and total cost. It ensures the bearing is securely located axially.
- High Radial Load Capacity: The single row deep groove construction is optimized to handle significant radial loads (dynamic: 4699 lbf, static: 3664 lbf), providing robust support for rotating shafts.
- Precision and Durability: Made from chrome steel rings and balls with a stainless steel cage, this bearing offers high strength, wear resistance, and corrosion resistance for reliable performance.
- Versatile Application Fit: As an open bearing without integral seals, it allows for custom lubrication solutions and is ideal for high-speed applications (up to 12,000 rpm) where minimal friction is critical.
206 NR Bearing Typical Application Areas
The 206 NR bearing is ideally suited for applications requiring compact design and secure axial location. Common uses include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
