6306-2ZNR Bearing Product Overview & Core Advantages
The 6306-2ZNR is a single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This shielded bearing features an integrated snap ring on its outer ring, enabling simplified axial positioning within a housing without the need for complex machining. Its metric dimensions (30mm bore, 72mm OD) and P0 tolerance class ensure consistent performance and easy integration. Pre-lubricated with grease, it offers a robust solution for applications requiring radial load capacity and maintenance-free operation.
6306-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| -2Z | Non-contact steel shields on both sides | Provides effective contamination protection while maintaining high-speed capability. |
| -NR | Snap ring groove and snap ring fitted on the outer ring | Facilitates secure axial location and simplifies housing design, reducing assembly time and cost. |
6306-2ZNR Bearing Structural Features & Performance Benefits
- Simplified Assembly & Positioning: The integrated snap ring (NR designation) allows for positive axial location, eliminating the need for complex housing shoulders or end caps. This feature is critical for applications where precise bearing positioning is required for optimal performance.
- Effective Sealing: The non-contact steel shields (2Z) effectively retain the factory-applied grease and protect the bearing's internal components from contaminants like dust and debris, significantly extending service life.
- Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing is designed to handle significant radial dynamic loads (6654 lbf) and static loads (3597 lbf), ensuring durability under demanding conditions.
- Maintenance-Free Operation: Pre-lubricated with grease and sealed, the 6306-2ZNR is ready for immediate use and requires no relubrication, reducing total cost of ownership.
6306-2ZNR Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Material Handling Conveyors
- Agricultural Machinery
- Pumps and Fans
- Any application requiring a reliable, easily mounted radial ball bearing with built-in axial positioning.
