6208-ZN/C3 Bearing Product Overview & Core Advantages
The 6208-ZN/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing features a shielded design on one side and a snap ring groove on the outer ring, offering effective contaminant protection and simplified axial location within a housing. Its C3 radial internal clearance makes it particularly suitable for applications involving thermal expansion or where interference fits are used, ensuring reliable operation under varying operational conditions. The combination of high-quality chrome steel construction and precision ABEC 1 | ISO P0 tolerances delivers consistent performance, high durability, and excellent value for a wide range of machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6208 | Standard deep groove ball bearing series with 40mm bore, 80mm OD, 18mm width. |
| Z | One side shielded with metal shield for basic contaminant exclusion. |
| N | Snap ring groove on the outer ring for axial location and simplified housing design. |
| C3 | Greater than normal radial internal clearance for applications with shaft/housing interference fits or thermal expansion. |
6208-ZN/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from high-grade chrome steel for both rings, balls, and cage, this bearing delivers a high radial dynamic load rating of 6542 lbf and a radial static load rating of 4002 lbf, ensuring reliable performance under significant radial loads.
- Optimized for Challenging Environments: The C3 internal clearance is a critical feature that accommodates dimensional changes caused by interference fits or operational heat, preventing premature failure due to excessive preload.
- Simplified Assembly and Retention: The snap ring groove (N) on the outer ring allows for secure axial positioning within a housing, eliminating the need for complex housing shoulders and reducing assembly time and cost.
- Contaminant Protection: The shielded (Z) side helps retain lubricant and exclude larger particulate contaminants, extending bearing service life in moderately dirty environments.
- Broad Operating Range: With a temperature range of -30°C to 120°C and a limiting speed of 8,300 rpm, this bearing is versatile for various industrial settings.
