6307-ZNRJEM Bearing Product Overview & Core Advantages
The 6307-ZNR is a single row deep groove ball bearing engineered for robust performance in radial load applications. Its defining feature is the snap ring groove on its outer ring, which facilitates secure axial positioning within a housing, simplifying assembly and reducing overall system costs. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable operation and is constructed entirely from chrome steel for durability. The inclusion of shields (Z) provides effective protection against contaminant ingress, making it a versatile and maintenance-friendly solution for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6307 | Standard bearing series designation, indicating a medium-duty, single row deep groove ball bearing with a 35mm bore, 80mm OD, and 21mm width. |
| -Z | Denotes a shielded bearing on one side, protecting the internal components from large particulate contaminants. |
| NR | Indicates the outer ring has a snap ring groove, allowing for secure axial location without the need for a complex housing shoulder. |
6307-ZNRJEM Bearing Structural Features & Performance Benefits
- Simplified Housing Design: The integrated snap ring groove eliminates the need for complex machining of housing shoulders, reducing manufacturing costs and assembly time.
- Effective Contamination Protection: The non-contact shield (Z) effectively prevents larger solid contaminants from entering the bearing, extending service life in challenging environments.
- Robust Load Capacity: The deep groove raceway and chrome steel construction provide high radial dynamic load rating (7509 lbf) and static load rating (4339 lbf), ensuring reliable performance under significant stress.
- Standard Precision & Clearance: Built to ABEC 1 (ISO P0) tolerance with CN group radial internal clearance, this bearing delivers consistent, reliable performance for general industrial applications.
6307-ZNRJEM Bearing Typical Application Areas
This bearing is ideally suited for applications requiring secure axial location and protection from debris. Common uses include:
- Electric Motors and Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Industrial Fans and Blowers
- Pump and compressor assemblies where a snap ring simplifies the housing design.
