6307 N Bearing Product Overview & Core Advantages
The 6307 N is a single row deep groove ball bearing designed for exceptional radial load capacity and high-speed operation. This precision bearing features a snap ring groove on its outer ring, enabling simplified axial location within a housing without the need for complex machined shoulders. Manufactured to P6 tolerance class, it delivers superior running accuracy, making it an ideal choice for applications demanding high reliability and precise rotational performance.
6307 N Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| N | Indicates a snap ring groove on the outer ring. This feature allows for secure axial positioning and can reduce housing design complexity and cost. |
| P6 | Denotes a tolerance class tighter than standard (Normal). This ensures higher running accuracy and is suitable for applications requiring precise shaft guidance. |
| CN | Specifies the standard radial internal clearance group for normal operating conditions. |
