206-2ZNR Bearing Product Overview & Core Advantages
The 206-2ZNR is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This shielded bearing features a snap ring on its outer ring, enabling secure axial location within a housing without requiring a complex housing shoulder. Its primary advantages include robust radial load capacity, simplified installation, and reliable operation due to its pre-lubricated and sealed design, making it an excellent choice for applications requiring high reliability and simplified maintenance.
206-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| -2Z | Non-contact steel shields on both sides | Provides effective protection against contamination while maintaining high-speed capability and low friction. |
| NR | Snap ring groove and snap ring on the outer ring | Facilitates secure axial location, simplifying housing design and assembly, enhancing bearing mounting stability. |
206-2ZNR Bearing Structural Features & Performance Benefits
- Robust Load Handling: The single row deep groove construction is optimized to carry significant radial loads, with a dynamic load rating of 4699 lbf and a static load rating of 3664 lbf.
- Simplified Axial Location: The integrated snap ring (fitted) eliminates the need for complex housing shoulders, reducing part count, assembly time, and overall system cost.
- Contamination Resistance & Longevity: The shielded (2Z) design effectively seals the bearing, protecting the chrome steel rings and balls from contaminants. Combined with pre-applied grease lubrication, this ensures long service life and maintenance-free operation in many environments.
- Precision & Speed: Manufactured to P0 tolerance class with a CN radial internal clearance, this bearing offers reliable and consistent performance. The stainless steel cage and optimized design support a limiting speed of 9,600 rpm.
206-2ZNR Bearing Typical Application Areas
This bearing is ideally suited for a wide range of applications where reliable radial load support and secure axial positioning are critical. Key industries and equipment include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Various automotive components and auxiliary drives
