6307-2ZNR/GJN Bearing Product Overview & Core Advantages
The 6307-2ZNR is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads. A key feature is its snap ring fitted on the outer ring (denoted by the NR suffix), which provides secure axial location within the housing, simplifying assembly and reducing overall design space. Combined with shielded seals (2Z), it offers robust protection against contamination, making it a versatile and durable solution for a wide range of industrial machinery.
6307-2ZNR/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| 6307 | Basic Bearing Series & Size | Indicates a medium series bearing with a 35mm bore, 80mm OD, and 21mm width. |
| 2Z | Non-Contact Shields on Both Sides | Provides effective protection against contaminants with minimal impact on limiting speed. |
| NR | Snap Ring Groove on Outer Ring | Enables secure axial location, eliminating the need for complex housing shoulders and reducing assembly costs. |
6307-2ZNR/GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing offers high strength and durability. With a dynamic load rating of 7509 lbf and a static load rating of 4339 lbf, it is built to withstand significant radial loads.
- Simplified Installation & Space Efficiency: The integrated snap ring (NR) feature allows for a compact housing design and ensures the bearing remains securely positioned, preventing axial creep under load.
- Enhanced Contamination Protection: The non-contact shields (2Z) effectively seal the bearing interior from dust and debris, extending service life and reducing maintenance frequency in harsh environments.
- Standard Precision & Clearance: Conforming to ABEC 1 | ISO P0 tolerance class and CN radial internal clearance, it provides reliable performance for general industrial applications.
6307-2ZNR/GJN Bearing Typical Application Areas
The 6307-2ZNR is ideally suited for applications requiring secure mounting and contamination resistance, including:
- Electric Motors
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
