209-2ZNR Bearing Product Overview & Core Advantages
The 209-2ZNR is a single row deep groove ball bearing engineered for high-performance industrial applications requiring reliable radial load capacity and robust operation. Its key advantages include shielded protection against contamination, a snap ring groove on the outer ring for simplified axial location, and pre-lubrication for immediate service. Manufactured with chrome steel rings and balls, it delivers dependable performance and long service life under standard operating conditions.
209-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 209 | Basic bearing series designation, defining the standard metric dimensions: 45mm bore, 85mm OD, 19mm width. |
| 2Z | Bearing is equipped with shields on both sides. This provides effective protection against solid contaminants while allowing for higher limiting speeds compared to contact seals. |
| NR | The outer ring features a snap ring groove and is supplied with a fitted snap ring. This facilitates secure axial location of the bearing within a housing, simplifying assembly and reducing the need for complex housing shoulders. |
209-2ZNR Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The single row deep groove raceway geometry is designed to carry significant radial loads efficiently, with a dynamic load rating of 7913 lbf and a static load rating of 6744 lbf.
- Controlled Internal Clearance: Manufactured with a standard CN group radial internal clearance, ensuring optimal performance and fit for a wide range of common industrial applications.
- Enhanced Operational Simplicity: The combination of non-contact shields (2Z) and pre-applied grease lubrication creates a maintenance-free solution, protecting the bearing from contamination and providing long-term, reliable operation within its specified temperature range of -30°C to 120°C.
- Robust Construction: Components made from chrome steel (rings and balls) and a stainless steel cage provide excellent durability, corrosion resistance, and consistent performance.
209-2ZNR Bearing Typical Application Areas
This bearing is ideally suited for applications requiring robust performance and easy installation, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery where snap ring location is specified for housing design.
