6206-ZNR/C3 Bearing Product Overview & Core Advantages
The 6206-ZNR/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric system bearing features a snap ring (fitted) on its outer ring, enabling secure axial location within a housing without the need for complex housing shoulders. Its shielded construction offers effective protection against contaminants while maintaining low friction. Pre-set with a C3 radial internal clearance, it is optimized for applications with expected thermal expansion or where interference fits are used, ensuring stable operation under varying thermal conditions. This combination of features makes it an excellent choice for applications requiring high reliability and simplified assembly.
6206-ZNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6206 | Standard bore diameter code for a single row deep groove ball bearing with a 30 mm bore. |
| Z | Denotes a shielded side. This is a non-contact metal shield that protects the bearing interior from large contaminants. |
| NR | Indicates the outer ring has a snap ring groove and a snap ring is fitted. This facilitates secure axial positioning. |
| /C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with anticipated thermal expansion or interference fits. |
6206-ZNR/C3 Bearing Structural Features & Performance Benefits
- Secure Axial Location: The integrated snap ring on the outer ring allows for simplified and secure mounting within a housing, reducing design complexity and assembly time.
- Contaminant Protection: The shielded (Z) design effectively prevents the ingress of large particulate contaminants, enhancing bearing service life in less-than-ideal environments.
- Optimized Internal Clearance: The C3 clearance group provides extra operational space between the rolling elements and raceways. This is critical for applications prone to thermal expansion, preventing pre-load and potential seizure, thereby ensuring reliable performance.
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a dynamic load rating of 4384 lbf and a static load rating of 254 lbf, making it suitable for moderate to high radial loads.
- Standard Precision: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring consistent quality and performance for a wide range of industrial applications.
6206-ZNR/C3 Bearing Typical Application Areas
The 6206-ZNR/C3 is ideally suited for a variety of industrial machinery and equipment where secure mounting and protection are key. Common applications include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., idlers, tensioners)
