207-2ZNR Bearing Product Overview & Core Advantages
The 207-2ZNR is a metric single row deep groove ball bearing designed for exceptional reliability in industrial applications. This shielded bearing features an integral snap ring on its outer ring, enabling simplified axial location within a housing without the need for complex machining. Manufactured to P0 tolerance class, it delivers consistent performance for general precision requirements. Its core advantages include robust radial load capacity, effective contamination protection from the Z-type shields, and the convenience of being pre-lubricated with grease for immediate, maintenance-free operation.
207-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| 2Z | Non-contact shields on both sides | Protects against contamination while maintaining high-speed capability and low friction. |
| NR | Snap ring groove and snap ring fitted on the outer ring | Simplifies assembly and provides secure axial location, reducing housing design complexity and cost. |
207-2ZNR Bearing Structural Features & Performance Benefits
- Robust Construction & High Rigidity: The single row deep groove raceway and chrome steel construction provide high resistance to deformation under radial loads, ensuring stable operation.
- Optimized Load Capacity: With a dynamic load rating of 6182 lbf and a static load rating of 4946 lbf, this bearing is engineered to handle significant radial forces in demanding applications.
