6308-ZN Bearing Product Overview & Core Advantages
The 6308-ZN single row deep groove ball bearing is a precision metric bearing engineered for reliable performance in radial load applications. Its key advantage lies in the snap ring groove on its outer ring, which enables secure axial positioning within a housing without complex machining, simplifying assembly and reducing total system cost. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent operation and is pre-lubricated for immediate use, making it an ideal maintenance-friendly component for a wide range of industrial machinery.
6308-ZN Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6308 | Basic bearing designation indicating a medium-duty, single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width. |
| Z | Denotes a shielded bearing on one side, protecting against contaminants. |
| N | Indicates a snap ring groove on the outer ring for secure axial location. |
6308-ZN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built entirely from chrome steel (rings, balls, and cage), this bearing offers high strength and durability. With a dynamic load rating of 915 lbf and a static load rating of 5395 lbf, it is well-suited for applications with significant radial loads.
- Simplified Housing Design: The integrated snap ring groove eliminates the need for complex shoulder machining or separate locking devices in the housing, reducing design complexity and assembly time.
- Contaminant Protection & Maintenance Reduction: The shielded (Z) design helps retain lubrication and exclude larger particulate contaminants, enhancing bearing life and promoting maintenance-free operation in many environments.
- Standardized Precision: Conforming to ABEC 1 | ISO P0 tolerance class and CN radial internal clearance, it ensures smooth, low-vibration running for general industrial applications.
6308-ZN Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable, cost-effective radial support.
