206-ZNR Bearing Product Overview & Core Advantages
The 206-ZNR is a single row deep groove ball bearing engineered for exceptional radial load capacity and reliable performance in demanding applications. This metric precision bearing features an integral snap ring on its outer ring, facilitating simplified axial location and secure mounting within housings. Manufactured from high-grade chrome steel with a stainless steel cage, it offers robust durability and consistent operation. Its shielded design and pre-lubricated state provide effective contamination protection and long-term, maintenance-free service, making it an ideal solution for applications requiring high reliability and simplified assembly.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 206 | Standard bearing series designation, indicating the bearing dimensions (30mm bore, 62mm OD, 16mm width). |
| Z | Signifies a shielded bearing on one side, protecting against contaminants. |
| NR | Indicates the outer ring has a snap ring groove and a fitted snap ring, enabling easy axial positioning. |
206-ZNR Bearing Structural Features & Performance Benefits
- Snap Ring for Secure Mounting: The outer ring is equipped with a snap ring (snap ring OD: 67.7mm), which acts as a positive locating feature. This simplifies housing design, eliminates the need for complex shoulder machining, and ensures the bearing remains securely positioned under axial loads and vibrations.
- Optimized Radial Load Capacity: The single row deep groove construction is designed to support high radial dynamic load ratings (4699 lbf) and radial static load ratings (3664 lbf), providing reliable performance in applications dominated by radial forces.
- Shielded & Pre-Lubricated for Longevity: The Z-shield effectively seals the bearing against dust and other particulates. Combined with factory-applied grease lubrication, this design offers long-term, maintenance-free operation, reducing total cost of ownership.
- Precision and Material Integrity: Built to P0 tolerance class with a CN radial internal clearance, this bearing ensures consistent and precise operation. The use of chrome steel rings and balls, paired with a corrosion-resistant stainless steel cage, guarantees high strength and extended service life.
206-ZNR Bearing Typical Application Areas
This versatile bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Agricultural Machinery and Conveyor Systems
- Industrial Pumps and Fans
- Material Handling Equipment
