6308-2ZN/C3 GJN Bearing Product Overview & Core Advantages
The 6308-2ZN/C3 GJN is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing features a shielded design on both sides, providing effective protection against contamination while maintaining low friction. Its key advantages include a high radial dynamic load rating of 915 lbf and a substantial radial static load rating of 5395 lbf, making it suitable for applications requiring reliable support under significant radial loads. The C3 radial internal clearance ensures optimal performance in applications with thermal expansion or where fit-up conditions require greater operational clearance.
6308-2ZN/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
- 6308: Basic designation indicating a single row deep groove ball bearing with 40mm bore, 90mm OD, and 23mm width
- 2Z: Bearing features contact shields on both sides for superior contamination protection
- N: Snap ring groove on the outer ring for secure axial positioning
- C3: Greater radial internal clearance than normal for applications with shaft expansion or misalignment
- GJN: Specific designator for snap ring groove and special internal specifications
6308-2ZN/C3 GJN Bearing Structural Features & Performance Benefits
This bearing's construction delivers exceptional performance through several key features:
