6308-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6308-2Z/C3 is a single row deep groove ball bearing designed for robust performance and long service life. Its key advantage lies in its ability to efficiently handle radial loads while also accommodating moderate axial loads in both directions. The combination of shielded construction and a C3 radial internal clearance makes it an excellent choice for applications requiring reliable operation under thermal expansion or heavy load conditions, offering a compact and cost-effective solution for a wide range of industrial machinery.
6308-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6308 | Standard bore diameter (40 mm), outside diameter (90 mm), and width (23 mm). | Defines the core bearing dimensions for interchangeability and fit. |
| 2Z | Bearing is equipped with shields on both sides. | Provides effective contaminant protection, retaining pre-applied grease and extending bearing life. It is a non-contact seal, minimizing friction. |
| C3 | Radial internal clearance greater than Normal (CN) group. | Accommodates thermal expansion in the shaft or housing, preventing preload and ensuring smooth operation under heavy loads or at elevated temperatures. |
6308-2Z/C3GJN Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 915 lbf and a radial static load rating of 5395 lbf, ensuring durability under demanding conditions.
- Optimized for Stability: The C3 internal clearance is a critical feature for applications where interference fits or operational heat generation are factors, preventing binding and maintaining performance.
- Reliable Shielding: The 2Z shields protect the bearing's internals from dust and debris without significant speed penalty, contributing to a maintenance-free design for the life of the lubricant.
- Precision & Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing guarantees reliable running accuracy and interchangeability for general industrial applications.
