6308-ZN/C3 Bearing Product Overview & Core Advantages
The 6308-ZN/C3 is a single row deep groove ball bearing engineered for robust performance in demanding applications. This precision bearing excels at handling high radial loads while accommodating moderate axial loads in both directions. Its defining features include a snap ring groove on the outer ring for secure axial location and a C3 radial internal clearance for stable operation under thermal expansion. Shielded on one side, it offers effective contamination protection, making it a reliable and high-rigidity solution for industrial machinery.
6308-ZN/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6308 | Basic Bearing Series & Size | Denotes a medium series deep groove ball bearing with 40mm bore, 90mm OD, and 23mm width. |
| Z | Shield on One Side | Provides effective protection against contaminants from one side while maintaining low friction. |
| N | Snap Ring Groove | Enables secure axial positioning and simplified housing design, enhancing assembly reliability. |
| C3 | Radial Internal Clearance | Greater than normal clearance for applications with shaft expansion or high operating temperatures. |
6308-ZN/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with chrome steel construction provides excellent radial dynamic load rating of 915 lbf and static load rating of 5395 lbf, ensuring stable operation under substantial loads.
- Secure Axial Location: The integrated snap ring groove prevents outer ring creep, simplifying housing design and improving system reliability in applications with vibration or axial forces.
- Optimized Thermal Performance: The C3 clearance accommodates differential thermal expansion between shaft and housing, preventing preload and ensuring smooth operation across the -30° to 120°C temperature range.
- Controlled Friction & Contamination Protection: The single shield effectively excludes large contaminants while maintaining low running torque. The unlubricated design allows for custom lubrication schemes tailored to specific application needs.
6308-ZN/C3 Bearing Typical Application Areas
- Electric Motors & Generators: Ideal for main shaft support in industrial motors requiring secure location and reliable performance.
- Gearboxes & Transmission Systems: Provides robust radial support in speed reducers and power transmission equipment.
- Material Handling Equipment: Used in conveyor pulleys, forklift wheels, and other machinery requiring bearings with locating features.
- Agricultural Machinery: Suitable for implement drives and PTO shafts where contamination resistance and secure mounting are critical.
- Industrial Pumps & Compressors: Handles combined loads in rotating assemblies where thermal expansion must be accommodated.
